Analyses performance of derict sequence spread spectrum with BPSK modulation

bpsk扩频调制,先进行扩频调制，再进行bpsk调制。有功率谱和频谱(First carries on the spread spectrum modulation, in BPSK modulation, frequency spectrum and power spectrum)

对802.11协议模拟的OFDM信号的两种速率6Mbps（BPSK调制）和12Mbps（QPSK调制）进行循环谱检测来验证对OFDM信号检测的可行性。(Cyclic spectrum detection is performed on two rates of OFDM signals simulated by the 802.11 protocol, 6 Mbps (BPSK modulation) and 12 Mbps (QPSK modulation) to verify the fea
