Abstract
Methods and apparatus are provided for adjusting receiver gain based on received signal envelope detection. The gain of a received signal is adjusted by obtaining a plurality of samples of the received signal for a given unit interval; determining an amplitude of the received signal based on the samples; and adjusting a receiver gain based on the determined amplitude. The received signal can be sampled, for example, using a plurality of latches. The value of the received signal can then be estimated by evaluating one or more of the latch values. Once the amplitude of the received signal is determined, one or more latches can be positioned at a desired target amplitude and the receiver gain can be adjusted until the amplitude of the received signal is within a desired tolerance of the specified target value.
