摘要
讨论了TK算法的原理和在GPS中TK算法的新应用。用TK算法估算出GPS多径信号相对于直射信号的码片延迟,使GPS直射信号经过一定的延迟后,与反射信号进行叠加,提高了直射信号的载噪比,进而达到反射信号增强直射信号的作用。验证了这一算法和结论。
This thesis studies the principal of the TK algorithm and its new application in GPS. It estimates the delay of the GPS multipath signal compared with the direct signal using the TK algorithm, based on the estimation, make a certain delay of the GPS direct signal, and then superposition the delayed signal with the reflect signal. In this way, the Carrier Noise Ratio (CNR) of the signal is enhanced. Therefore, it achieves the purpose of using the reflect signal to enhance the direct signal. The method is simulated with MATLAB, and the results are presented .
