A system and method are provided for estimating interference power at a receiver antenna in a communications systems receiver, in which an interference type signal associated with a received radio signal is detected, an in-band interference power associated with the received radio signal is determined, and an interference power at the antenna is estimated using the determined in-band interference power and the detected interference type. Estimating the interference power at the antenna includes interpolating the determined in-band interference power using scaling factors determined by the interference type signal associated with the received radio signal. The system and method determine in-band carrier power associated with the radio signal based on a channel estimate h(k), and the in-band interference information is based on interference samples I(n). In addition, an average total power, automatic gain control (AGC) setting, and signal-to-information-and-noise ratio can be determined by the system and method. |
