Abstract:
1. A process for controlling a target signal to interference ratio (SIR) in a communication system, the process comprising: receiving a series of actual error signals, wherein each actual error signal includes a quantity of data blocks and a quantity of data blocks in error; determining a size of a sliding window; filtering the series of actual error signals within the sliding window; computing an expected error signal within the sliding window; determining whether the target SIR will increase or decrease; and generating a correction signal by comparing the filtered series of actual error signals and the expected error signal, wherein the correction signal is set to zero when it is determined that the target SIR will increase and the expected error signal is greater than the filtered actual error signal and the correction signal is set to zero when it is determined that the target SIR will decrease and the expected error signal is less than the filtered actual error signal.
