Keeping in mind, the end goal to accomplish such requests is multi-user Direct Sequence Code Division Multiple Access (DS-CDMA). Here DS-CDMA is considered as a framework with multi clients who need to send Colour video information. This paper recommends a new Crossover Blend of Kalman Filter and Rake (CBKFR) -based spreading codes generator for multi-user Direct Sequence Spread Spectrum (DSSS) correspondence frameworks. Execution of this framework under different channels, code Sequences and modulation schemes are analysed and discussed. The performance is evaluated in terms of Bit Error Rate (BER) for various values of Signal to Noise Ratio (SNR). The obtained outcome demonstrates that the average BER is 0.32339 and 0.157071 respectively with conventional rake receiver and proposed CBKFR receiver when SNR value is 20dB. Hence it is found that the performance of the proposed CBKFR receiver is more preferable in comparison with conventional Rake receiver. Furthermore, the proposed CBKFR receiver is the most efficient and reliable for improving BER performance for DS-CDMA multipath channels.
