Abstract:
The research entails the development of a WCDMA system model in an indoor environment that transmits data over an Additive
White Gaussian Noise channel. In this environment the data rate is taken as 2Mbps. The performance of this model is enhanced
by employing convolution coding scheme which reduced the error rate encountered in the system. The results show that the
performance of the system improves when convolution coding is implemented. The performance of QPSK is found to be better
that that of 16-QAM which means that QPSK is an efficient modulation scheme but its throughput is less that of 16-QAM.
Therefore, there must be a trade-off between the modulation format to be applied in a given system and the error rate generates
at the receiver by that format. The convolution coding improves the power efficiency of the system when it is incorporated into
the system.
