Abstract: The invention provides a multipath diversity receiving equipment of CDMA system, including: a sample quantization device, a sample data storage device, a code data storage device, a mulitpath resource management device, a code resource management device, a demodulation control device, a correlation demodulation device, a channel estimation unit, a energy accumulation device, and a energy analysis processing device. The multipath demodulation, multipath search and delay phase locked loop are all seen as the multipath demodulation, only the energy accumulation should be implemented for multipath phase of the multipath search and delay phase locked loop after the demodulation. The invention combines the multipath demodulation, multipath search and delay phase locked loop together through the hardware, and at the same time with the demodulation control unit , not only realizes the parallel demodulation of multiple multipaths by controlling the correlation demodulation device, but also realizes the operation of the N-dimension matrix, so as to provide the function extension of the combination detection.

Abstract translation: 本发明提供了一种CDMA系统的多径分集接收设备，包括：采样量化装置，采样数据存储装置，码数据存储装置，多路径资源管理装置，码资源管理装置，解调控制装置，相关 解调装置，信道估计单元，能量积累装置和能量分析处理装置。 多径解调，多路径搜索和延迟锁相环都被视为多路径解调，解调后只能对多路径搜索和延迟锁相环的多径相位实现能量累加。 本发明通过硬件将多径解调，多路径搜索和延迟锁相环组合在一起，同时与解调控制单元相结合，不仅通过控制相关解调装置实现多路径的并行解调，而且实现了 操作N维矩阵，从而提供组合检测的功能扩展。
