Abstract

Optimum diversity combining and equalisation applied to linear systems is realised using maximum likelihood sequence estimation. It is shown that each received signal should be applied to a filter which is matched to the corresponding diversity channel´s impulse response. The output of this set of filters is simply summed, sampled at the symbol rate and input into a maximum likelihood sequence estimator. The performance of this structure is predicted by simulation with MSK and GMSK modulations using a GSM channel model. Even though GMSK is not linear, the nonlinearity is ignored and the receiver structure is made the same in both cases
