Virtual antenna arrays for future wireless mobile communication systems

Abstract

A novel approach extending the possible applicability of recently emerged space time codes was introduced. It was suggested to let spatially adjacent mobile stations (MSs) co-operate with each other leading to diversity and coding gains. By means of analysis, these mobiles from a virtual antenna array were introduced. This approach successfully deals with the problem of just one receiving antenna in a handset. The idea was to relay the information from the base station (BS) antenna array using a variable number of relaying MSs. The effect of different possible configurations on the performance in terms of bit error rate (BER) versus signal-to-noise-ratio (SNR) was analyzed. The results were very promising in the initial stage of development. (5 References).
