Abstract
The present invention is a method and apparatus for reducing transmission errors by a base station when transmitting a communication signal. An RF communication signal is received at the base station and analyzed for errors. A correction signal is then generated based upon the analysis. Prior to transmission of the communication signal from the base station, the communication signal is corrected using the correction signal.
Claims2
A method for reducing transmission errors by a base station when transmitting a communication signal, comprising the steps of:
- receiving an RF communication signal at said base station;
- filtering said received signal to generate a filtered signal using a weighting signal;
- analyzing said received signal for errors;
- demodulating said received signal to generate a plurality path values for each multipath component in said received signal;
- generating a correction signal based upon said analysis;
- mixing said path values with said correction signal to generate said weighting signal;
- and
- correcting said communication signal using said correction signal prior to transmission of said communication signal from said base station.
