| 摘 要： | 载波频率估计是实现扩频信号盲估计的关键技术之一,提出一种载波估计新方法,信号经过延迟相乘后,经功率谱运算,实现对直接序列扩频(DS/SS)信号的载波频率估计,并进行仿真验证,结果表明,应用该方法能够简单的估计出载频.

| Abstract: | A new method to estimation the carrier frequency in direct sequence spread spectrum(DS/SS) is proposed.Delay-and-multiply is used and the amplify module is analyzed,when the delay time is the 1/4 of the chip time,power spectrum is calculated and the carrier frequency in DS/SS is realized.Simulation result shows that it is easy to estimate the carrier frequency with this method. |

| Keywords: | DS/SS carrier frequency delay-and-multiply power spectrum estimation |
