To minimize the overall transmit power while maintaining a constant data rate and target BER, a downlink adaptive resource allocation algorithm with G type channel estimated error at the base station is proposed for multiuser space-time block coding and beam forming (STBC-BF) MIMO-OFDM system in correlated channels. The algorithm allocates the subcarriers with the shared manner. A null steering processing...
To minimize the overall transmit power while maintaining a constant data rate and target BER, a downlink adaptive resource allocation algorithm with jointing the exclusive manner and the shared manner is proposed for multiuser MIMO-OFDM system in correlated channels. The algorithm allocates all the subcarriers to different users according to their spatial correlations. The users with high spatial...
