用m序列过低通滤波器模拟产生带限高斯白噪声，m序列的长度足够长时功率谱特性接近高斯白噪声的特性。(M-sequence low-pass filter with analog band-limited white Gaussian noise generated, m length of the sequence is long enough the power spectral characteristics close to Gaussian white noise characteristics.)

非持续性CAMA是一种冲突避免的CSMA协议，如果终端检测到信道状态空闲，则立即进行数据传输，而信道状态忙，则停止载波监听，并随机在等待一段时间后再进行载波监听。(Non-durable CAMA avoid CSMA protocol is a kind of conflict, if the end channel state idle, detected immediately for data transmission, the channel state is busy, stop the carrier sense, and random carrier sense of the reentry after waiting for a period of time. )
