针对多输入多输出正交频分复用图样选择峰均比(peak-to-average-power-ratio PAPR)抑制算法需要传递边带信息的缺点,提出了一种无边带信息传输的图样选择峰均比抑制算法.该算法利用不同分布图样的梳状导频携带加扰相位序列选择信息,结合浅海水声信道的稀疏特性在接收端对加扰图样进行自主区分,实现了无边带信息的图样选择峰均比抑制.仿真和水池实验结果证实:无边带信息传输的图样选择峰均比抑制算法可以在不损失PAPR抑制性能的前提下,准确解算出传输相位序列选择信息、对抗突发噪声、实现无边带信息传输的可靠水声通信.
In view of the shortcoming that the peak-to-average-power-ratio (PAPR) suppression algorithm needs to transmit the sideband information for multi-input multi-output Orthogonal Frequency Division Multiplexing pattern, a pattern selection peak without sideband information transmission Average ratio suppression algorithm.The algorithm uses the comb-shaped pilot of different distribution patterns to carry scrambling phase sequence selection information and combines the sparse characteristics of the shallow sea acoustic channel to autonomously distinguish the scrambling patterns at the receiving end, thereby realizing the pattern of borderless information And the peak-to-average ratio suppression is selected.The simulation and the experimental results show that the peak-to-average ratio suppression of the pattern selection in the no-band information transmission can accurately calculate the transmission phase sequence selection information without any loss of PAPR suppression performance against the burst noise, Reliable underwater acoustic communication for the transmission of borderless information.
