ABSTRACT:
The apparatus and method for estimation and minimization of the carrier multipath response envelope are disclosed. The reduction of the carrier multipath error signal is achieved by using the weighted or modified tracking or estimation circuits. The Modify and Weight signals are generated by the generator of Modify or Weight signals at five different circuit levels.
