摘要
在包交换同步码分多址 (P- SCDMA:Packet- Switch- Synchronious Code Division Multpiple Access)系统的扩频序列的捕捉方案基础上 ,建立了信号模型并运用 m序列部分相关的统计结论从理论上对捕捉系统的参数进行了分析 ,给出了在 AWGN环境下虚警概率对 EC/N0 、检测概率对 EC/N0 的图像。所用的研究方法和有关部分相关捕捉的结论也适用于其它直接扩频快速捕捉系统 ,如 IS- 95。
Based on the spread-spectrum code acquisition scheme of P-SCDMA ( Packet-Switch-Synchronous Code Division Multiple Access) , the paper sets up a signal model and analyzes parameters of the acquisition system theoretically with the statistical result of partial-correlation of m sequence. Figures of false-alarm probability versus E_c/N_o and figures of detection-probability versus E_c/N_o on AWGN condition are presented. The research method and the result of partial correlation acquisition detection can also be used in any other fast acquisition system, such as IS-95 system.
