Abstract

A statistical power adjustment scheme for systems employing adaptive modulation and coding as well as multicodes is proposed. The scheme adjusts the transmit power level, based on the statistics of the received signal-to-interference ratio, in order to achieve a target bit rate outage probability. It is shown that the required power adjustment can differ greatly depending on the channel parameter values, even though without power adjustment these values support the same average bit rate.

Keywords: Adaptive systems Bit rate Downlink Error analysis Modulation coding Multiaccess communication Probability Quality of service Throughput Wireless networks
