A method and apparatus for estimating the presence of RF interference in a wireless data channel is described. The method and apparatus comprises a set of identical tracking / register (T / R) filter blocks, each T / R filter block associated and corresponding to an RF channel of interest. Each T / R filter block includes a pair of tracking / register (T / R) filters. Power / magnitude estimates from an RSSI calculation are input to the T / R filter blocks. One T / R filter is used to estimate the noise floor (in the absence of interference). The T / R filter latches and filters the lowest input values received from a power / magnitude circuit. The other T / R filter estimates the level of an interferer, if present, by latching and filtering the largest valued outputs of the power / magnitude circuit.
