A MULTIUSER APPROACH TO NARROW-BAND 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 mu ltiuser approach allows us to derive a maximum-likelihood multiuser re ceiver and its reduced-complexity suboptimal version, Finally, a decor relating diversity receiver, which seeks a tradeoff between performanc e and complexity, is studied, Closed-form performance parameters are d erived for ail the proposed receivers in the case of coded coherent PS K and independent frequency nonselective Rayleigh fading.
