说明： OFDM系统的PAPR性能与分割方式有关，但除此之外还与输入数据的子分组数V、相位集合中的相位数P以及子载波数量N有关。下面，对各种条件下PTS-OFDM系统的性能进行了仿真。(PAPR performance of OFDM systems and partitions the way, but in addition to the input data, the number of sub-group V, number of phases in the collection phase P and N on the number of subcarriers. Here, a variety of conditions PTS-OFDM system performance is simulated.)
