Abstract:
1. A method for estimating interference power present at a receiver antenna in a communications systems receiver, comprising: detecting an interference type signal associated with a received radio signal; determining an interference power, measured at baseband, associated with the received radio signal; estimating an interference power present at the antenna using the determined baseband interference power and the detected interference type, wherein the step of estimating the interference power present at the antenna comprises: determining carrier power, measured at baseband, associated with the radio signal based on a channel estimate h(k), and further wherein the baseband interference information is based on interference samples I(n); determining an average total power for the communications systems receiver at the receiver antenna, wherein the step of determining the average total power for the communications systems receiver at the receiver antenna comprises: determining an automatic gain control (AGC) setting based on the determined average total power, and determining a signal-to-noise-plus-interference ratio (SINR), wherein the SINR is equal to the ratio of the average carrier power at the receiver antenna to the average interference power at the receiver antenna.
