Abstract

Disclosed herein are methods and apparatus for generating digital receiver and transmitter AGC values for a spread spectrum transceiver. A method includes the steps of (a) integrating the power of a received and sampled signal; (b) calculating a logarithm of the received integrated power; (c) subtracting a predetermined reference value from the logarithm of the power to generate a first error signal; (d) filtering the first error signal; (e) comparing the filtered first error signal to a predetermined first threshold; (f) incrementing or decrementing a first counter value and resetting a filter accumulator as a function of the result of the step of comparing; and (g) converting the first counter value to an analog voltage for controlling the gain of a spread spectrum receiver amplifier. The logarithm is preferably the second logarithm of the power. The method further includes generating a transmitter AGC value.
