A multiuser approach to narrowband cellular communications
We compare three receivers for coded narrowband transmission affected by fading and co-channel interference. The baseline receiver is based on conventional diversity reception with maximal-ratio combining, A multiuser approach allows us to derive a maximum-likelihood multiuser receiver and its reduced-complexity suboptimal version, Finally, a decorrelating diversity receiver, which seeks a tradeoff between performance and complexity, is studied, Closed-form performance parameters are derived for ail the proposed receivers in the case of coded coherent PSK and independent frequency nonselective Rayleigh fading.
