Research on Capture Performance of CDMA2000 Reverse Link
This paper analyzes characteristics of CDIMA2000 reverse link HPSK modulation pattern, establishes the model of mobile station transmitted signals and observation station received signal and deduces flow of capture using R-PICH. In order to analyze quantitatively the influence to capture performance of detection threshold, integration time, signal-tointerference ratio and vestigial carrier, in the Neyman-Pearso criterion, the functional relationship between false-alarm probability and detection probability and the computational formula, are deduced, which provides theoretical support for optimal design of parameters. Aim at the impact of inserted forward power control group and vestigial carrier, the solution of short-term coherent integration associating with long-term incoherent accumulate is proposed, and the calculation method of capture performance in this mode is deduced. Simulation results show that the scheme can achieve stable capture toward mobile station under low SNR and effectively promote capture performance.
