Abstract

The propagation channel of a mobile radio system exhibits severe signal shadowing and multipath fading, which results in wide variation of signal-to-interference ratio (SIR) at the receiver. To tackle this problem, power control is used to maintain the desired link quality and thus achieve higher capacity. In order to mitigate the channel variation effect precisely, a new application of grey theory [1] to the power-control strategy in the direct-sequence code-division multiple-access cellular mobile systems is introduced in this paper. This scheme aims to predict SIR affected by the channel variation at the receiver and issue appropriate control signal to the transmitter. The simulation results indicate that the grey-based scheme can offer less outage probability than the previous mechanisms.
