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.
