Based on joint time and frequency offset estimation, a reliable signal detection scheme is obtained by modulated pilot symbols using an m-sequence.
方案利用时频联合估计来得到可靠的信号检测，并从导频符号估计时间和频率偏移。

The paper first introduces the selected mapping method for the reduction of the peak-to-average power ratio of OFDM signals, and a method for improving SLM using m-sequence is put forward.
在研究用选择性映射降法降低OFDM系统峰均功率比的基础上，提出了用m序列对SLM方法进行改进。

The selection of the initial shift register of M-sequence is a key technique in pulse compression waveform design whose pulse compression waveform must have low peak power and large compression ratio.
