ABSTRACT:
Determination of a received signal strength indication in a direct conversion receiver begins by determining, at a given time, a 1stvalue to be the larger of the in-phase component of the received signal and the quadrature component of the received signal. The direct conversion receiver then determines a 2ndvalue at the given time to be the smaller of the in-phase component of the received signal and the quadrature component of the received signal. As such, at a given time, the 1stand 2ndvalues correspond to the greater and lesser of the in-phase component and quadrature component, respectively. Having obtained these values, the direct conversion receiver then determines the received signal strength indication based on the 1stvalue, the 2ndvalue and an offset value. The offset value provides a scaling of the RSSI value based on the range of the RSSI values.
