Communication Theory Evaluation of SIR statistics in a DS/CDMA system with signal-level-based power control and multipath dispersion

The statistical evaluation of the estimated short-term signal-to-interference ratio (SIR) for power control is presented in many-to-one reverse link. As mentioned in other previous works, the statistical evaluation shows that the estimated short-term SIR can be approximated by a log-normal distribution. The analysis has applications to a cellular system employing direct-sequence spread-spectrum code-division multiple access (CDMA) with M-ary orthogonal modulation on the uplink. Copyright © 2004 AEI.
