Ashwani Awasthi, Deepak Singh, Vikas Srivastava · Proceedings of the Conference on Advances in Communication and Control Systems-2013 · 2013
This paper presents a study of the QPSK (Quadrature Phase Shift Keying) modulation technique using rician channel in CDMA (Code division multiple access) systems. The selection of good modulation technique is a important factor for analyzing the performance of communication system. The simulated result of this modulation technique demonstrates the efficient BER performance result which is important for mobile communication. In this technique, modulation is achieved by varying the phase of the basis functions depending on the message symbols. We will use MATLAB 7.4 for simulation & calculation of BER and SNR for CDMA System.
