The case for multiply-detected macrodiversity scheme in mobile systems

The multiply-detected macrodiversity (MDM) is based on post-detection combining; i.e., it is a macrodiversity scheme with a number of received signals being detected and a decision algorithm being employed to maximize the probability of correct decision. We compare the performance of the MDM scheme with the traditional S/I-diversity and show the achievable improvement. As a rule of thumb, improvement of two orders of magnitude in the BER is possible for small number of interferers.
