INTRODUCTION:

LAB ELECTRONICS CDMA Trainer provides a basic understanding of the concepts behind CDMA and various concepts needed to be considered in case of CDMA system design such as pseudo random bit signal generation, the spreading and dispreading of data sequence, Direct Sequence Spread Spectrum (DSSS) generation and decoding , digital modulation and demodulation for BPSK and PWM.
