ABSTRACT:
A reduced speed equalizer is provided which receives signal samples at a first rate but performs the equalizing operation at a second, lower rate which is below the rate at which symbols are transmitted across the channel. The equalizer is docked to receive samples in a shift register at the first rate. Samples stored in the shift register are clocked into a set of buffers at the second rate. The equalizer coefficients are applied to the samples stored in the buffer set to generate a sequence of equalized symbols at the second rate.
