Abstract
In this paper a new Transmit Power Control (TPC) scheme is proposed for SINR-based fast PC algorithms using frcquency-mutiplexed pilot symbols on the uplink of a WCDMA Rayleigh fading mobile radio channel with multi-path. The performance of various PC techniques is evaluated by means of Monte Carlo computer simulation. The WCDMA modem considered includes different coding schemes and a matched filter RAKE combining receiver. The objective is to investigate the effects of the number of resolvable propagation paths, the antenna diversity reception scheme employed and the coding scheme used on the performance of the fast power controlled WCDMA receiver in a Rayleigh fading single-cell environment. The results obtained indicate that the unbalanced PC algorithms outperform the conventional balanced PC algorithms. It is also theoretically proved that the unbalanced PC algorithms have better tracking ability than the conventional PC algorithms.
