摘要 针对码捕获中门限设置的复杂性,提出了一种过门限捕获与选取最大值相结合的码捕获准则(简称TC/MAX准则),并将此准则应用于直扩超宽带通信系统码的捕获。理论分析和计算机仿真表明,采用TC/MAX准则可获取比过门限捕获更好的捕获性能。 Due to the difficulty of threshold setting in code acquisition, a new hybrid criterion called TC/MAX （threshold crossing/maximum selection） was presented for code acquisition. To test the proposed criterion, the general formulation was applied to the particular case of ultra wide bandwidth （UWB） communication systems. Analysis and simulation show that the proposed scheme can improve the probability of detection significantly, compared with TC criterion.
