Qr-Rls Adaptive Digital Filter With 18-Bit Pipeline Architecture

View page
US Patent:
8599903, Dec 3, 2013
Filed:
Aug 27, 2010
Appl. No.:
12/869875
Inventors:
Brandon P. Hombs - Merrimack NH, US
Joseph A. Farkas - Merrimack NH, US
Leonard E. Russo - Nashua NH, US
Joshua D Niedzwiecki - Manchester NH, US
Assignee:
Collision Communications, Inc. - Portsmouth NH
International Classification:
H04B 1/707
US Classification:
375146
Abstract:
A QR-RLS adaptive digital filter provides fast computation without excessive computational resources. 18-bit multipliers enhance speed, and a floating point inverse square root block adjusts dynamic range in 12-dB steps. A memory stores two P-matrix copies, one being delivered with rows shifted according to the clock speed so as to enhance pipeline processing. Embodiments reliably detect modulation schemes, demodulate strong signals by passing feedback bits between multiple stages, remove impulses due to lightening, etc, erase symbol estimates which exceed an error threshold, and add high frequency noise to avoid mathematical divergence caused by excessive S/N. A genetic method is provided for identifying asynchronous spreading codes with minimum correlations, whereby randomly selected candidates compete based on Frobenius norms of their correlations, the weakest being discarded and the process being iterated. A method is provided for selecting optimal filter sampling windows for simultaneously detected symbol streams having relative timing delays.

Tree Structured Multicarrier Multiple Access Systems

US Patent:
20060120471, Jun 8, 2006
Filed:
Dec 1, 2005
Appl. No.:
11/291883
Inventors:
Rachel Learned - Waltham MA, US
Brandon Hombs - Merrimack NH, US
Assignee:
BAE SYSTEMS Information and Electronic Systems Integration Inc. - Nashua NH
International Classification:
H04B 1/707
H04K 1/10
US Classification:
375260000, 375144000
Abstract:
A Tree-structured multicarrier multiple access communication system in a multiple access environment having a number of interfering signals. In one embodiment an environment estimator estimates and tracks the number of interfering signals of the environment. A code selector determines an optimal spreading code represented by the environment, and identifies an actual spreading code that is closest to the optimal spreading code. A signal transmitter can then be used to transmit a multicarrier multiple access signals in accordance with the actual spreading code identified. On the receiver side, a multiuser detector (MUD) module performs tree structured multiuser detection signal processing, and produces a bit stream for each interfering signal.

Media Access Control Protocol For Multiuser Detection Enabled Ad-Hoc Wireless Communications

View page
US Patent:
20110051674, Mar 3, 2011
Filed:
Sep 25, 2009
Appl. No.:
12/742686
Inventors:
Joshua D Niedzwiecki - Manchester NH, US
Brandon P Hombs - Merrimack NH, US
Assignee:
BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH
International Classification:
H04W 40/00
H04W 72/04
US Classification:
370329
Abstract:
A method is disclosed for increasing the communication capacity of a shared ad-hoc wireless channel by using multiuser detection (MUD) to distinguish overlapping information transmitted simultaneously by a plurality of nodes. The transmitting nodes simultaneously provide parameter-estimating signals over separate, unshared, low-rate parameter channels generated using orthogonal frequencies, spread spectrum technology, or time multiplexing. Receiving nodes use these separate, non-overlapping parameter-estimating signals to estimate MUD-required signal parameters such as amplitude, phase, and frequency offset, thereby enabling use of lower complexity MUD receivers, because the parameters are not estimated in the presence of other interference. Node ID, spreading code type, and/or other information can also be transmitted over the parameter channels. Limiting the number of parameter channels can limit the maximum number of transmitting nodes. Amplitudes of parameter channel transmissions can be greater than communication channel transmissions by a known ratio. Parameter channels can be frequency-hopped for jam-resistance.

Power Aware Scheduling And Power Control Techniques For Multiuser Detection Enabled Wireless Mobile Ad-Hoc Networks

View page
US Patent:
20120250595, Oct 4, 2012
Filed:
Feb 23, 2011
Appl. No.:
12/932318
Inventors:
Joseph Farkas - Merrimack NH, US
Brandon P. Hombs - Merrimack NH, US
International Classification:
H04W 52/02
H04W 84/18
H04W 52/24
US Classification:
370311, 370342
Abstract:
What is provided is a system for maintaining acceptable error rates in a MUD-enabled ad-hoc network. In this system the power spread associated with all of the nodes is maintained within the dynamic range of the system, for instance 30 dB. Also, the signal-to-noise ratio at an intended receiver is maintained above a predetermined minimum SNR, for instance above 5 dB. If the dynamic range rule is not met, then the power at the transmitting node is attenuated such that the dynamic range rule is met, checking to see that the minimum SNR rule is also met, or the transmission from this node is pulled. If there is no power control solution, then power aware scheduling is applied. Alternatively, only power aware scheduling is utilized.

Visual Communications System Employing Video Imagery

US Patent:
20140036103, Feb 6, 2014
Filed:
Jul 29, 2013
Appl. No.:
13/952777
Inventors:
Brandon P. Hombs - Merrimack NH, US
Alexander M. Wyglinski - West Boylston MA, US
Assignee:
BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH
International Classification:
H04N 5/232
US Classification:
3482221
Abstract:
A system and method for platform independent LOS visual information transmission is disclosed. A transmitter consists of a series of sequential images that are stacked together to form frames in a video transmission. Each image is modulated spatially, by color, and by intensity. The data is transmitted over an LOS visual channel. The receiver first captures each individual image from the received video, and then demodulates each image in the three areas it was modulated spatially, by color, and by intensity. LOS visual information transmission allows for secure data transfer and reduces interference from other applications.

US Patent:
20190165985, May 30, 2019
Filed:
Jan 9, 2019
Appl. No.:
16/244064
Inventors:
- Peterborough NH, US
Brandon Hombs - Merrimack NH, US
Sagar Dhakal - Bedford NH, US
Joseph Farkas - Merrimack NH, US
International Classification:
H04L 27/26
H04L 25/02
H04B 7/0452
H04B 7/024
Abstract:
Methods and systems for performing compressed time domain joint channel estimation in a multi-user MIMO wireless network include receiving training signals from a plurality of users, estimating a maximum delay spread for the received data according to a coherence bandwidth of the received data, limiting the received data in the time domain to the estimated maximum delay spread, selecting and estimating an active tap from the limited data set, and subtracting a contribution of the selected active tap from the reduced data set. These steps can be repeated until the residual signal falls below a specified minimum. The network can be a C-RAN network. The training data can be SRS or DMRS data. Limiting the received data ensures that only a few significant taps are analyzed, so that the system is not under determined and can be analyzed for accurate channel estimation using any of several existing algorithms.
