| 摘 要： | 构建了一种适于匙孔信道的满码率极化准正交空时分组码以改善其误比特率性能,采用快速最大似然译码算法进行译码,并与匙孔信道的传统准正交空时分组码、单中继瑞利信道和单中继匙孔信道的极化准正交空时分组码分别进行误比特率的仿真和比较.结果表明:在相同SNR条件下,本文构建的分组码比传统准正交分组码具有更低的误比特率;与两种单中继极化准正交空时分组码相比,在SNR较高情况下本文分组码具有更好的性能.

| Abstract: | To improve the performance of bit error rate of keyhole channel,a rate one quasi-orthogonal space time polarization block code(QSTPBC) is proposed in this paper.The fast maximum likelihood sequence decoding method is used.This QSTPBC is compared with the traditional quasi-orthogonal space time block code(QSTBC) for keyhole channel,single relayed QSTPBC for Rayleigh channel and keyhole channel,respectively.Simulation results show that the performance of the new QSTPBC is better than that of the traditional Q... |
