Single Wavelength Source-Free Ofdma-Pon Communication Systems And Methods

View page
US Patent:
20100215368, Aug 26, 2010
Filed:
Aug 21, 2009
Appl. No.:
12/545159
Inventors:
Dayou Qian - Plainsboro NJ, US
Neda Cvijetic - Plainsboro NJ, US
Junqiang Hu - Princeton NJ, US
Ting Wang - Princeton NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
H04J 14/00
US Classification:
398 67
Abstract:
Methods and systems for processing communication signals in an Orthogonal Frequency Division Multiple Access (OFDMA)-Passive Optical Network (PON) are disclosed. An optical carrier at a wavelength generated at an optical line terminal (OLT) may be reused by optical network units (ONUs) in the network for upstream transmission of data signals to the OLT. In addition, each ONU may perform carrier suppression to avoid broadband beating noise resulting from the simultaneous transmission of upstream data signals on the same wavelength. Further, the optical source at the OLT used to generate the optical carrier may be reused as a local oscillator for coherent detection of received upstream signals to minimize any frequency offsets.

Efficient Square-Root Free 2 Symbol Max-Log Receiver

US Patent:
20120250804, Oct 4, 2012
Filed:
Mar 29, 2012
Appl. No.:
13/433873
Inventors:
Narayan Prasad - Wyncote PA, US
Neda Cvijetic - Plainsboro NJ, US
Sampath Rangarajan - Bridgewater NJ, US
Ting Wang - W. Windsor NJ, US
Assignee:
NEC LABORATORIES AMERICA, INC. - Princeton NJ
International Classification:
H04L 27/06
US Classification:
375341
Abstract:
The present invention employs a look up table based implementation for the metric computations which eliminate redundancy and substantially reduce the number of multiplications. Moreover, inventive method exploits the fact that the un-normalized constellation symbols are complex integers so that the product of a real-number and an un-normalized constellation symbol can be implemented by only additions. The inventive method also enables a greater efficiency for whitening colored noise prior to demodulation, one of which involves no square-root operation. The invention results in less complexity, faster operation, lower power consumption, without sacrificing performance

Polmux-Ofdm-Dd Transmitter And Receiver For Reduced Complexity And Overhead In Optical Access/Metro Transmission

US Patent:
20120263467, Oct 18, 2012
Filed:
Apr 13, 2012
Appl. No.:
13/446306
Inventors:
Neda Cvijetic - Plainsboro NJ, US
Narayan Prasad - Wyncote PA, US
Ting Wang - West Windsor NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
H04J 14/06
US Classification:
398 65
Abstract:
An optical communication system includes a polarization multiplexed orthogonal frequency-division multiplexing POLMUX-OFDM transmitter for generating a POLMUX-OFDM double sideband signal, an optical processing path for processing the double sideband signal from the transmitter; an analog-to-digital convert ADC-OFDM receiver coupled to the optical processing path for receiving the double sideband signal processed by the optical path; and a block-diagonal multiple-input multiple-output MIMO equalizer responsive to the receiver for enabling correct operation for a completely random incoming signal polarization state without adaptive polarization control at said receiver, which enables complexity.

US Patent:
20120294614, Nov 22, 2012
Filed:
May 14, 2012
Appl. No.:
13/470425
Inventors:
Neda Cvijetic - Plainsboro NJ, US
Milorad Cvijetic - Tucson AZ, US
Ming-Fang Huang - Atlanta GA, US
Ezra Ip - Plainsboro NJ, US
Ting Wang - W. Windsor NJ, US
Assignee:
NEC LABORATORIES AMERICA, INC. - Princeton NJ
International Classification:
H04J 14/00
US Classification:
398 67
Abstract:
A method by an optical network unit ONU includes, for downstream transmission, using a first tunable laser for coherent detection on a sub-band basis to increase receiver sensitivity and reduce analog-to-digital conversion ADC and digital signal processor DSP requirements within the ONU, and for upstream transmission, using a second tunable laser and using an optical signal beating between the first and second tunable lasers to generate a tunable radio frequency RF signal source for upstream multi-band OFDMA signal generation thereby avoiding need for an otherwise more costly RF clock source within the ONU, enabling low-speed digital-to-analog conversion DAC operation and rendering the ONU colorless in both optical and radio frequency RF domains.
