Recently, the capacity of the broadcast channel with multiple antennas is investigated. Various space-time (ST) processing techniques to adapt channel conditions are utilized to increase capacity. Precoding becomes vital to deal with interferers and cooperation problems efficiently. ST codes will be investigated in conjunction with precoding. We aim to investigate channel adaptive ST coding and precoding techniques to achieve the maximum capacity with practical quality of service requirements. Although the capacity is extensively investigated, implementation methods are relatively less investigated. This project is to fill the cap between implementation (ST coding and precoding methods as outcomes) and theory (capacity analysis).Read moreRead less
