摘要：A combined, parallel adaptive equalizer/echo canceller is disclosed. The equalizer/canceller receives at least one input signal which is split into n taps. The n taps are multiplied by corresponding n tap coefficients to produce n tap output signals. The n tap output signals are then processed through an additive pipeline to produce a filter output signal. The additive pipeline provides low latency by processing the nth most recent tap output signal n clock cycles from the filter output signal. The combined FIR filter structure is made fully adaptive using delayed LMS coefficient adaptation. Tap coefficients are updated using an error signal and delayed versions of the input signal. The error signal is a product of a calculated error and a negative adaptation factor. The delay is equal to a sum of n+1 cycles.
