Abstract

We investigate spectrum shaping based on cyclic filtering for coded single-carrier transmission over intersymbol interference (ISI) channels. An optimized precoder is derived for coded single-carrier systems using an iterative linear-minimum-mean-square-error (LMMSE) frequency-domain-equalization (FDE) receiver. Numerical results show that this precoder can provide considerable spectrum-shaping gain.
