The performance of MIMO system depends highly on the accuracy of channel state information and the inter-cell interference is one of the major restrictive factors influencing on the performance degradation in LTE systems. In this paper we propose a new method to work out the desired channel from the received signal. According to the similar principle, each interference channel is also obtained simultaneously,...
This paper proposes a spatial time-division multiple access (STDMA) based scheme (STBS) to enhance the system throughput in cognitive radio wireless networks. Especially, the proposed scheme is suitable for the situation when the available number of channels is far less than the number of secondary users (SUs). The system design includes: 1) a novel criterion based on SINR constraint (SC) to determine...
