摘要:
A digital receiver system to recover signals from inter-symbol-interference includes a finite impulse response (FIR) filter using convolution to recover signals; and a channel estimator coupled to the FIR filter to estimate FIR coefficients, wherein the channel estimator uses a second order expectation and a fourth order expectation from a convolution to calculate error function.
