Patent ID: 7433402

Claim:
A receiver responsive to an n o plurality of entry points comprising: a feedforward filter structure having an n o ×n i plurality of FIR filters where n i is an integer greater than 1 and that is not restricted to equal n o , each responsive to a signal that comprises blocks of N f symbols each, that is derived from one of said n o entry points and each developing an output signal that contributes to one of n i feedforward filter structure outputs, with each of said FIR filters in said feedforward filter structure having N f filter taps; a feedback filter structure developing n i feedback signals, the structure having an n o ×n i plurality of FIR filters, each being responsive to one of n i receiver output signals; a subtractor structure that develops n i signals from signals of said n i feedforward filter structure outputs and said n i feedback signals; and decision logic responsive to said n i signals developed by said subtractor structure, for developing said n i receiver output signals.
