Compression of Single User BPSK an Multi User 2-PSK Transreceiver System

The typical three path propagation and anti jamming capability associated with DSSS were carried out through the combination of Lab VIEW and MATLAB 7.8. At the transmitter, the NRZ data stream is first mapped into BPSK symbols and then spread-out using different PN code like Hadamard code, Gold or Kasami sequences. And we see that single user is not total utilization band. Direct Sequence Spread Spectrum (DSSS) techniques are used same bandwidth Number of user to increase, and we see that better performance. That we can say Direct Sequence Spread Spectrum techniques is reused to bandwidth. And we can say that in this techniques power loss is low, anti jamming capability is less and system is more reliable. Furthermore, BPSK-Spreading transceiver should be analyzed for their performance, multipath scenario and interference whether under AWGN channel which show that these has been overcome effectively and attain more robust performance, when using direct sequence spread spectrum.
