| 摘 要： | 针对非协作通信中平坦衰落条件下单天线接收两路MSK混合信号分量的幅度估计问题,提出了一种基于max - min思想的幅度盲估计算法.该算法采用混合信号幅值序列中多个极大极小幅值的估计值来进行混合信号分量的幅度估计,并采用加窗局部极值平均的方法来获得多个极大极小幅值的估计值.仿真结果表明:在信噪比大于10 dB条件下,该...

| Abstract: | For non cooperative communication,an amplitude estimation a
lgorithm is proposed for two-way MSK mixing signals with single antenna u
n
der flat fading channel. Legions of maximum and minimum amplitudes of the mixtu
r
e are obtained by caculating partial mean of maximum or minimum values within a
window and applied to estimate amplitudes of signal components. Simulation resu
lts show its good performance when SNR is greater than 10dB and perfect robust p
erformance for the changes of the power ratio between signal components and diff
erence of time delay. As a non preamble aided algorithm with low
er complexity,it is significant for following blind processing. |
