The signal strength of a received signal in a communication system is estimated by the measured signal strength of a desired signal which is transmitted from a source device to a destination device. The energy of the desired signal and the energy of the noise are measured or computed. The measured signal strength can be computed by dividing the energy of the desired signal with the energy of the noise. The signal strength of the desired signal can be estimated as the maximum likelihood estimate of the actual signal strength .alpha.. The signal strength of the desired signal can also be estimated based on the expected value of the energy of the desired signal. The signal strength of the desired signal can further be estimated based on the expected value of the energy of the desired signal and accounting for a predetermined bias.
