| 摘 要： | 多相关器技术被广泛的应用于多径抑制和自主完好性监测等算法中,但采用传统结构实现会带来计算量的显著增长。提出了一种高效的多相关器实现技术,利用伪码差分序列中非零个数远少于采样点数的特点,采用差分结构实现多相关器以减少计算量和硬件规模。研究结果表明,在相关器间隔为1/16码元宽度条件下,其计算量只有传统结构的1/32,硬件规模只有传统结构的1/8。

| Abstract: | Multiple correlators are widely used for mulipath mitigation and Receiver Autonomous Integrity Monitoring(RAIM),but using conventional structure can dramatically increase the amount of computation.An efficient method for the applications which use multiple correlators has been developed.It utilizes the feature that the number of non-zero values in differential pseudo-code sequence is much smaller than that of samples.The differential structure is used to reduce the amount of computation and the scale of har... |
