Patent ID: 6870882

Claim:
A receiver responsive to an n o plurality of entry points comprising: a feedforward filter structure having an n o ×n j plurality of FIR filters, each responsive to a signal that is derived from one of said n o entry points and each developing an output signal that contributes to one of n j feedforward filter structure outputs; a feedback filter structure developing n j feedback signals, the structure having an n j ×n i plurality of FIR filters, each being responsive to one of n j output signals; a subtractor structure that develops n j signals from signals of said n j feedforward filter structure output and said n j feedback signals; decision logic responsive to said n j outputs developed by said subtractor structure, for developing said n j output signals; and a sampling circuit interposed between said n o plurality of entry points and said feedforward filter structure that samples received signal at rate T a = T I , where I is an integer and T is symbol rate of a transmitter whose signals said receiver receives.
