一种低信噪比环境下的PN码捕获策略

Strategy of PN Sequence Capture Used in Low SNR Condition

本文提出一种在CDMA系统中称为多符号累加斜率法的PN码捕获方法,在保证很高的捕获灵敏度的前提下,可获得大的动态捕获范围。

In this paper, a strategy of PN sequence capture used in the low SNR condition, called multisymbol accumulation and slope,is presented.The result of applying it to the CDMA system shows that the method obtains high capture sensitivity and broad capture range.
