1. A method for use in wireless equipment for processing a received signal, the method comprising the steps of:

  • (a) selecting one of a number of attenuation states as a function of a measured signal strength associated with the received signal, each attenuation state associated with a respective attenuation level of the received signal;

    (b) in the selected attenuation state, measuring a signal to noise ratio (SNR) associated with the received signal;

    (c) changing the attenuation state to a new attenuation state selected from one of the number of attenuation states;

    (d) in the new attenuation state, measuring another SNR associated with the received signal; and

    (e) changing the attenuation state back to the selected attenuation state if the measured SNR in step (d) is not greater than the measured SNR in step (b).
