Abstract

In this paper, an analytical and simulated approach has been developed for evaluating the performance of Bit Error Rate (BER) of Direct Sequence Spread Spectrum (DSSS). It is also demonstrated in this paper that how BER can be minimised using Rate Transition techniques. The work uses effective spreading sequence to achieve variable data rate transmission. In this research work, blind detection of the user signal has been considered assuming the receiver has prior knowledge of the user’s spreading code and is synchronised by using increased matched filter gain. Thus, it is not required to control the information to be transmitted along with the user signal. An attempt has also been made to show that how bandwidth utilisation has been halved using multirate techniques. This innovative research findings make use of implementing an efficient DSSS with reduced BER.
