This paper presents a demodulator based on the downlink of WCDMA,uses FPGA to implement the demodulator,and gives the whole structure of the demodulator and its logic design.The demodulator demodulates the chip's data from the NodeB,and transmits the results to PCs in a real-time way with an integrated MCU.The demodulator can be configured flexibly and can demodulate the information of multiple users and cells,and features the ability of real-time general processing.
