ADAPTIVE DIRECT CONVERSION RECEIVER
First Claim
1. A method for reducing a rate of error in an output of a receiver comprising:
- calculating a rate of error associated with a received signal at a first time;
comparing the rate of error at the first time to a first threshold rate of error;
if the rate of error at the first time exceeds the first threshold rate of error, increasing current provided to a mixer in the receiver;
calculating a rate of error associated with a received signal at a second time;
comparing the rate of error at the second time to a second threshold rate of error; and
if the rate of error at the second time is less than the second threshold rate of error, resetting the mixer current.

Abstract
A method and apparatus is disclosed for improving performance of a communication receiver. An exemplary method comprises calculating a rate of error associated with a received signal at a first time; comparing the rate of error at the first time to a first threshold rate of error; if the rate of error at the first time exceeds the first threshold rate of error, increasing current provided to a mixer in the receiver; calculating a rate of error associated with a received signal at a second time; comparing the rate of error at the second time to a second threshold rate of error; and if the rate of error at the second time is less than the second threshold rate of error, resetting the mixer current.
