| 摘 要： | GPS件接收机在低信噪比的环境中,普通捕获算法不能实现理想的捕获效果.采用增加相干积分时间、处理相干积分后的数据和改进传统非相干算法的方法,显著提高了信噪比,有效地消除了传统非相干算法中的平方损耗.通过对不同的捕获算法仿真比较得出,改进的算法有更强的信号检测能力,处理增益更高.

| Abstract: | In the low SNR environments,such as indoor and in forests,common algorithm could not attain ideal acquisition results.By increasing time of coherent integral,processing data of coherent integral and ameliorating traditional non-coherent algorithm,SNR is improved remarkably and square loss of traditional non-coherence algorithm has been eliminated effectively.By comparing with other acquisition algorithms,simulation results denote that the ameliorated algorithm provides stronger capacity of detecting signal ... |
