Abstract
Described embodiments apply equalization to an input signal to a receiver such as a serial-deserializer. The receiver has an analog-to-digital converter (ADC), an M-way parallelizer, N serial buffers, N prefix buffers, and N decision feedback equalizers (DFEs), where M and N are greater than one. The ADC digitizes the input signal to form digitized symbols. The parallelizer assembles the digitized symbols into parallel sets of M digitized symbols. Each serial buffer has slots of M locations per slot and stores one set of M digitized symbols in one of the slots. The DFEs are responsive to common tap weight coefficients and produce parallel sets of M recovered data bits. Each DFE is first trained using sets of past digitized symbols loaded into a corresponding one of the prefix buffers and then processes digitized symbols stored in a corresponding one of the serial buffers.
