The research in this paper focuses on the Rake receiver technology for PRACH channel,which is one of the WCDMA uplink physical channels.The first part describes the structure and characteristics of PRACH channel.The theory and FPGA application of Rake receiver are presented secondly.The FPGA,with its high-speed parallel computing capability,is suitable for parallel multichannel computing and multi-user detection and demodulation,so the FPGA is considered for receiveing of WCDMA uplink and downlink signals.The use of rake receiver for uplink and downlink signal reception of WCDMA communication system is by far the most common practice.At last,the design is validated by the engineering implementation and the experiments.
