51389 针对在湍流信道下空间脉冲位置调制（SPPM）系统误码性能较差的问题，文章将空时分组码与空间调制技术结合，提出了基于比特补码正交空时分组码的空间脉冲位置调制（BCOSTBC-SPPM），利用空时编码增加信息冗余度以改善系统误码性能。 The system performance of Spatial Pulse Position Modulation(SPPM) is poor in turbulent channels. In order to solve this problem, the bit complement orthogonal space time Block Coding for Spatial Pulse Position Modulation(BCOSTBC-SPPM) is proposed by combining space-time block codes with spatial modulation technology to improve the bit error rate performance using the space-time coding information redundancy.
51390 同时基于最大似然（ML）检测推导了系统的理论误比特率上界，并通过蒙特卡洛仿真对理论上界进行了验证。 Based on Maximum Likelihood(ML) detection, the bit error rate expression of the proposed modulation is derived and is verified by Monte Carlo simulation.
51391 仿真结果表明，BCOSTBC-SPPM的误码性能相比SPPM有较大提升。 The simulation results show that compared with SPPM, the error performance of BCOSTBC-SPPM is greatly improved.
51392 在弱湍流信道下，当系统误比特率为10-4时，（4，2，4）-BCOSTBC-SPPM相比（4，1，4）-SPPM信噪比改善约10 dB。 At the bit error rate of 10-4, (4, 2, 4)-BCOSTBC-SPPM improves the signal-noise ratio by about 10 dB when comparing with(4, 1, 4)-SPPM under weak turbulence.
51393 该方式相较于传统正交空时编码方案在频谱效率方面有一定提升， Compared with the traditional orthogonal space-time coding scheme, this method has a certain improvement in spectrum efficiency,
51394 实现了系统有效性和可靠性的合理权衡。 and realizes a reasonable trade-off between system effectiveness and reliability.
51395 为了降低带宽阻塞率，节约频谱资源，在动态业务到达的弹性光网络(EONs)场景下，不同业务请求的路径状况可能不同， In order to reduce the bandwidth blocking rate and the consumption of spectrum resources in dynamic networks, the path conditions of different service requests may be different.
51396 因此不能确定单路径专有保护与带宽分割多路径专有保护的优劣。 Therefore, it is impossible to determine the advantages and disadvantages of single-path dedicated protection and partitioning dedicated path protection.
