Recently, there has been much interest in modulationtechniques to achieve transmitdiversity motivated by the increased capacity ofmultiple-input multiple- output (MIMO)channels. It is affordable to equip base stationswith more than one antenna, but it isdifficult to equip the small mobile units with morethan one antenna. In such a case,transmit diversity can only be achieved through usercooperation leading to what is knownas cooperative diversity. Cooperation provides a newdimension over which higher diversityorders can be achieved.In this thesis, we consider the design of protocolsthat allow ...
