  • Jan 2014
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 an...

... August 2015 specified for WCDMA. Sufficient literature [2,6] show that 16-QAM performance degrades heavily as the data rate is increased, but its chief advantage is an increased data throughput compared to lower order modulations. Hence the application of a coding scheme in this study. ...
Improving Quadrature Amplitude Modulation (16QAM) Performance in Wide band Code Division Multiple Access using Convolutional Coding
Article
Full-text available
  • Aug 2015
The performance of 16 QAM modulation techniques has been analyzed and improved for Wide band Code Division Multiple Access (WCDMA) applications at variable data rate. Matlab and Simulink have been used in the evaluation and the BER with and without coding has been compared as the data rate was increased from 64 kbps to 2MBps. It has been concluded that when convolutional coding was applied, the BER has could be improved by 0.54 % at 64 kbps, 0.39 % at 144 kbps, 0.78 % at 384 kbps and 0.53% at 2 MBps, all this being compared to a communication system without coding. Thus we can enhance the performance of a 16 QAM modulations by convolutional coding
