Design of Experiment System for Digital Signal Processing in Reverse Link of CMDA Communication System

The experiment system is designed for digital signal processing in the reverse link of CDMA communication system with the digital signal processor (DSP)-TMS320VC5416 of TI as the CPU. The signal processing is complex in the reverse link of the CDMA communication system, so it is difficult to observe and research the signal processing. However, in this experiment system, the results of the signal processing can be observed and researched distinctly, due to the rapid and precise operational capability, the general input and output ports of DSP and rich display characteristics of Code Composer System (CCS). The design of the hardware circuit and the displays of spread spectrum and OQPSK modulation are given
