【摘要】 研究了一种对信道矩阵进行等对角QR分解的联合编/解码算法,与传统对信道矩阵进行SVD分解算法不同之处在于,该算法将MIMO信道分解为多个相同的并行子信道,与VBLAST检测算法结合起来具有复杂度低,易于实现的优点。仿真结果表明采用该算法的SER性能优于除MLD以外算法的性能,并进一步从信道容量的角度证明了采用该算法,在高信噪比下所获得的信道容量与注水功率算法和等功率算法是相同的。更多还原

【Abstract】 In this paper a joint transceiver design that uses equal-diagonal QR decomposition with VBLAST decoder for MIMO systems has researched.The scheme is different from conventional SVD decomposition for MIMO channels in that it decomposes MIMO channels into multiple identical parallel sub-channels,which can make it convenient to design coding/decoding scheme.Our simulation results prove that using this scheme the SER performance is more optimal than any other methods proposed in this paper except MLD,and it also proved that this scheme is asymptotically optimal for high SNR in term of channel capacity.更多还原
