Abstract

The flexibility and design power inherent in the generalized-eigenfilter approach to sophisticated least-squares FIR-filter design problems is here demonstrated by using it to address a classic problem: the MMSE design of a (nonadaptive) fractional-tap-spacing linear equalizer and matched filter. The solution accounts for the analog filters and minimizes a combination of noise variance, mean-square intersymbol interference (ISI), and mean-square adjacent-channel interference (ACI)
