Abstract

We compare the output MSE of various linear multiuser receivers for a multiple-access asynchronous Gaussian slowly time-varying channel with multiple observations. We focus on a fractionally-spaced linear receiver and evaluate its bit error rate with uncoded transmission. Numerical examples based on a narrowband FDMA/TDMA channel (the uplink of a GEO satellite system) are given
