TL;DR: The structure of MLSE-based optical receivers operating in the presence of dispersion and amplified spontaneous emission, as well as shot and thermal noise, are discussed, and a theory of the error rate of these receivers is developed, and computer simulations show a close agreement between the predictions and simulation results.

TL;DR: This paper presents the architecture and circuit design of a single chip 32 mm2 90 nm CMOS DSP transceiver for electronic dispersion compensation (EDC) of multimode fibers at 10 Gb/s, based on maximum likelihood sequence detection (MLSD).

TL;DR: The architecture of a single-chip dual-polarization QPSK/BPSK 50 Gigabits per second (Gb/s) DSP-based transceiver for coherent optical communications is presented and a novel low-latency parallel-processing carrier recovery implementation which is robust in the presence of laser phase noise and frequency jitter is proposed.

TL;DR: In this article, the authors proposed a multi-channel equalizer that can compensate for channel-dependent impairments by adapting the feed-forward equalizer and the channel estimator for the Viterbi decoder.

TL;DR: In this paper, a coefficient generator generates filter coefficients using an error vector and input samples, and a filter stage generates equalized samples from input samples using the filter coefficients, where the received samples are provided by a receiver front end in an optical transmission channel carrying transmitted symbols.
