ABSTRACT:
In methods and apparatus for estimating carrier-to-interference ratios of signals transmitted between cellular radio base stations and mobile units, a SAT signal is transmitted from a base station to a mobile unit served by that base station. The mobile unit receives the SAT signal and retransmits the received SAT signal to the base station. A first order autoregressive parameter is calculated for the received SAT signal at the base station is correlated with a tabulated carrier-to-interference ratio estimate to estimate the carrier-to-interference ratio of the signals.
