对信号进行离散傅立叶变换，完成对信号的频谱分析(fft analysis)

The 802.11 standard specifies a carrier sense multiple access with collision avoidance(CSMA/CA) protocol. In this protocol, when a node receives a packet to be transmitted, it first listens to ensure no other node is transmitting. If the channel is clear, it then transmits the packet. Otherwise, it chooses a random "backoff factor" which determines the amount of time the node must wait until it is allowed to transmit its packet. During periods in which the channel is clear, the transmitting node decrements its backoff counter.

基于LMS自适应时延估计算法,可以进行时间延迟的估计。(Delay estimation algorithm based on LMS adaptive research based on the fractional lower order time delay estimation algorithm, including: covariation-based time delay estimation, based on the fractional lower order covariance delay estimation method, as well as the minimum norm when the average P delay estimation method.)

设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK a variety of modulation and corresponding demodulation mode, the main (sub-coherent and non-coherent) and bit error rate statistics, and compared with the theoretical value , a graphical representation of the bit error rate and SNR relationships.)
