Performance of Optimum Detector Structures for Noisy Intersymbol Interference Channels,

摘要

When transmitting digital information by radio or wireline systems,errors may arise from additive noise and from successively transmitted signals interfering with one another. This report presents new results on evaluating the probability of error, i.e. performance,of optimum detector structures which are obtained when compound statistical decision theory is used to unravel noisy intersymbol interference patterns in the received signal. It includes a comparative study of the performance of certain detector structures and approximations to them,and the performance of a transversal equalizer. The report also shows that the optimum compound statistical decision procedure is not equivalent,either to subtracting out the interfering energy from the received signal,or to gathering together the energy which is dispersed throughout the received signal.
