Lecture
This lecture covers the RAKE receiver for DSSS and CDMA, focusing on the performance in multipath channels with AWGN. It explains the despreading process, autocorrelation functions, and the impact of using a RAKE on the SINR. The lecture also discusses the matched filter for multipath channels, the signal space representation, and the code division multiple access (CDMA) uplink. Various topics such as Walsh-Hadamard sequences, CDMA application in UMTS/HSDPA downlink, and the challenges of asynchronous CDMA uplink are explored.
