Abstract
A feedback equalizer includes a summing unit having an output and first input for receiving a modulated signal, which includes a symbol defined by a first number of chips. A subsymbol processor is coupled to the output of the summing unit. The symbol processor is capable of generating a subsymbol waveform upon receipt of a second number of chips of the symbol. The second number is less than the first number. A feedback filter is coupled to a second input of the summing unit and the symbol processing unit to selectively filter the subsymbol waveform from the modulated signal.
