Macrodiversity technique for improvement in BER in wireless systems

The authors analyse a novel macrodiversity scheme, the multiplydetected macrodiversity (MDM) scheme, whch relies on postdetection combining, as opposed to the traditional macrodiversity techniques, which are selection-based. The average fraction of the cell area is evaluated with an improved bit error rate (BER) performance, average BER improvement, and improvement in the average outage probability, relative to three other selection-based macrodiversity schemes. As a point of reference, the average improvement in BER is always at least one order of magnitude throughout at least 25% of the cell area, when the probability of the co-channel interferer's presence is not >70%.
