余弦波 meaning in Chinese

cw cosine wave

Abstract : a method by using 8031 single - clip microprocessor to get the syntonical bit information is presented , based on the characteristic of the modulated singal in ascending cosine envelope . the timer is locked at the maximum of the wave peak . the experiment results indicate that this method is feasible for 2 400 bps system
文摘:利用升余弦包络调制信号的特点，即基带信号为升余弦波，接收端可以利用这一包络，从中提取定时信息.提出了一种将时钟锁定到包络峰值最大点的单片机实现的方法，从而完成了在接收端正确提取定时信息的任务
