【摘要】 提出了一种基于凸优化理论的多用户MIMOSDMA联合发送—接收优化系统.在此系统中,将各用户的比特误码率作为目标函数通过凸优化理论来得到发送权矩阵和接收权矩阵,使系统在各用户同时达到最优的接收性能.模拟结果表明,这样得出的MIMOSDMA系统性能比传统的以最小均方误差为标准的系统性能有明显的改善.更多还原

【Abstract】 A multiuser MIMO SDMA joint Tx-Rx optimization system is proposed based on the convex optimization theory, and each user’s BER is taken as the objective function. With the proposed algorithm, transmit and receive matrices are obtained to achieve the least BER. Simulation shows that performance of the designed SDMA system is obviously better than the conventional system which uses mean square error as its cost function.更多还原
