信号峰均比PAR(Peak-to-AverageRatio) 概念引入:无线信号从时域上观测是幅度不断变化的正弦波,幅度并不恒定,一个周期内的信号幅度峰值和其他周期内的幅度峰值是不一样的,因此每个周期的平均功率和峰值功率是不一样的。在一个较长的时间内,峰值功率是以某种概率出现的最大瞬态功率,通常概率取为0.01%。在这个概率下...
1.由于功率的峰均比是电压的峰均比的平方,PAR一般是指功率的峰均比,但也有书上把他当做电压的峰均比来用。 2.如果功率幅值随时间没有变化,即“包络的最大值”与“包络的平均值”处处相等,即“恒包络”信号的峰均比为1或者是0dB。 8楼2022-07-06 03:27 回复 L木-木 3.如果只考虑一个周期的无线...
