Abstract :
Generally, the conventional 2D-RAKE receivers are based on the second-order statistics while assuming perfect array conditions. However, the sensor response, location uncertainty, and the use of sample statistics can severely degrade the performance of second-order statistics processing. In this paper a cumulant-based 2D-RAKE receiver for synchronous CDMA system with decorrelator is presented. Employing cumulant-based signal processing technique the proposed 2D-RAKE receiver is blind and demonstrates excellent performance.
