摘要:
为进一步提高多输入多输出(MIMO)双向中继系统性能,该文在梯度下降法的基础上,引入用户端功率分配和发射预编码与接收波束成形,结合中继站波束成形矩阵和分配功率相,构成一个完整的联合交替迭代结构(AIS); 通过固定变量循环计算,逐个得到各个变量的最优值。仿真表明,与梯度下降法、迫零和最小均方误差加注水功率分配法相比,该文交替迭代结构方法的速率有所提高,误码性能提高较明显。当误码率等于10-2时,与3种算法中最优的梯度下降法相比,该文方法可获得2.5 dB的信噪比增益。
Abstract:
To improve the performance of the multiple-input multiple-output(MIMO)two-way relay system,a complete alternating iterative structure(AIS)based on the gradient descent method(GDM)is proposed here.The AIS is combined with the transmit precoding,the receive beamforming at user terminals and the power allocation(PA)at relay station to form a large iterative loop.Simulation results show that the proposed AIS performs better than the existing schemes like the GDM,the zero forcing plus water filling PA(WFPA),and the minimum mean square error plus WFPA in terms of the sum-rate and the bit error rate(BER).In particular,when BER is 10-2,the proposed scheme gets 2.5 dB signal-noise-ratio(SNR)gain over the best one of the existing three schemes.
