To Improve the BER and Channel Capacity Through the Implementation of Differential Noise Shift Keying Using Matlab

摘要

Objectives: To improve the factors such as BER (Bit Error Rate), Channel Capacity, Gain and SNR (Signal to Noise Ratio) using the enhanced technique. Methods/Statistical Analysis: We proposed a new efficient technique called Multiple Access Differential Noise Shift Keying (DNSK) along with convolution detector based on the modulation and demodulation. Findings:The proposed modulation configurations are specified, analytical terminologies intended for Bit Error Rate are derived and it verified by computer simulations over Rayleigh, Gaussian and Additive White Gaussian Noise (AWGN). The simulation result shows that the proposed method overtakes classical noise shift communication schemes regarding bit error rate (BER) in the multiuser state. Application/Improvements:In existing method the improvisation of Bit Error Rate and gain has done by Chaos shift Keying and it achieves the Bit Error Rate and gain at the rate of -0.003 and 0.5 dB respectively. In our research the modulation and demodulation has done by Differential Noise Shift Keying and achieves the Bit Error Rate and Gain at the rate of 0.1 and 1.12 respectively.
