Continuous time filter-decision feedback equalizer architecture for optical channel equalization

摘要

A communication system having a transmitter transmits an information signal over a communication media and a receiver coupled to the communication media receives the transmitted information signal. The receiver includes a continuous time filter having an adjustable bandwidth for linearly equalizing the transmitted information signal as a function of the adjustable bandwidth. A decision feedback equalizer coupled to the continuous time filter then reduces inter-symbol interference in the filtered information signal.
