摘要: 对于单载波区块传输的时域波束成型和频域等化共同设计问题,在这篇论文当中,我们提出一个有效的次最佳化演算法。因为波束成型的权重和等化器的系数可以被一起设计,我们所提出演算法的误码率相较于其他论文,有相当程度的下降。另外,因为接收端的波束成型是实作在前快速傅立叶转换之前,我们提出的演算法相较于后快速傅立叶转换波束成型有较低的计算复杂度。模拟结果显示,我们提出的演算法可以在适当的次数下收敛。
A joint multiple-input multiple-output (MIMO) time domain beamforming and frequency domain equalization (FDE) method for single-carrier block transmission (SCBT) is formulated as an optimization problem and solved by an efficient suboptimal algorithm in this thesis. Because the beamforming weights and the equalizer coefficients are jointly designed, the BER performance of the proposed algorithm is much better than other algorithms in the literature [2,3,4,5,7,8]. Also because the beamforming at receiver is performed before the FFT operation, the proposed algorithm has much lower computation complexity than those post-FFT beamforming methods [2,3]. Our simulation results show that this algorithm converges within a reasonable number of iterations.
