Electronic Pre-Distortion Operating at 1 Sample/symbol with Accurate Bias Control for CD Compensation
Coherent communications Fiber optics links subsystems
2015/6/9
Electronic pre-distortion operating at 1 Sa/sym with anti-aliasing filter and accurate bias control is proposed. This approach guarantees Q penalty within 0.7 dB for 112 Gb/s DP-QPSK coherent system w...
Coherent CD Equalization for 111Gbps DP-QPSK with One Sample per Symbol Based on Anti-Aliasing Filtering and MLSE
Fiber optics communications Coherent communications
2015/6/9
W e propose a coherent detection scheme with one sample per symbol. MLSE is used to compensate for ISI introduced by anti aliasing filtering. 50,000 ps/nm of CD is fully compensated with only 1 dB pen...
A 30 GHz Bandwidth, 80 GS/s Sample Rate Real-time Waveform Digitizing System
GHz Bandwidth GS/s Sample Rate Real-time Waveform Digitizing System
2015/6/4
A method employing a unique mixture of microwave and digital signal processing is described that provides for large bandwidth increases in waveform digitizers. Such digitizers are a critical component...
