We propose and evaluate a single-bit adaptive step-size closed-loop power control (AS-CLPC) scheme which is adaptable to a dynamically changing radio channel. We also investigate the effect of the mobile terminal (MT) velocity on system performance when the proposed AS-CLPC scheme is employed. The proper power control constant of the AS-CLPC scheme is obtained by solving a polynomial equation. Compared with the IS-95 single-bit fixed step-size CLPC scheme, the proposed single-bit AS-CLPC scheme can reduce link margin (LM) by about 3 dB when the outage probability is below 0. 03 and a single fading path reception in the base station is assumed. System performance such as link availability and throughput can be improved by utilizing this proposed CLPC scheme in the outdoor radio propagation channel where time-selective fading occurs.
