摘要：
This paper is intended to develop a pivotal digital modulation system which provides efficient data transmission. Here Rayleigh and Rician channels are subject to test and an effective modulation scheme is developed in conjunction with simplicity and security. The proposed effective modulation scheme is a blend of scrambling the input bit stream and then performing an orthodox modulation in OFDM. Various modulation techniques are contemplated in this study. The above stated structure is developed in simulink and the proposed structure delivers the desired significant results. The simulation results show noteworthy elevation in the system performance in contrast to its contemporaries in bit error rate. The increase in transmission efficiency of the system which is reconstructed using our decoding technique is witnessed using MATLAB simulation results.
