摘要:为了更有效地降低滤波器组多载波(filter bank multicarrier,FBMC)系统过高的峰均功率比(peak-to-average power ratio,PAPR),在部分传输序列(partial transfer sequence,PTS)方法的基础上提出了多随机分割算法,该算法通过选用合适的子块数分割方法来降低系统的复杂度,同时兼顾了随机分割法的优越性。此外,根据其在分割顺序上的特点,可以进一步提高系统的性能。通过仿真试验验证了新算法的有效性。
In order to reduce high peak-to-average power ratio (PAPR) of the FBMC (filter bank multicarrier) system, we proposed a multi-random segmentation algorithm based on the PTS (partial transfer sequence)method. This method decreases the complexity of the system by selecting the appropriate subblock segmentation method, and takes account of the superiority of the random segmentation method. Its performance in the order of segmentation can further improve the performance of the system, and the validity of the new algorithm is verified by simulation.
