Design of a Practical DSSS Communication System Based on TMS320c5416 DSP

Direct sequence spread spectrum technology is very important in wireless telecommunication systems and data communication systems because it has many advantages, such as good concealment, and being able to overcome the multiple access interference. A practical DSSS communication system based on TMS320c5416 Digital Signal Processor is designed in the paper, which consists of baseband modulator, IF modulator/demodulator, local oscillator, antenna, Liquid crystal displays monitor and TMS320c5416 DSP, etc. The experiment result of transmission shows that the direct sequence spread spectrum system designed can realize effective data transmission and anti-interference communication with advantages of high data transmission rate and wide spectrum range.
