On the architecture and performance of an FFT-based spread-spectrum downlink RAKE receiver
2001
IEEE Transactions on Vehicular Technology
This paper describes a spread-spectrum downlink RAKE receiver that computes a data detection in the frequency domain. We assume a pilot signal is transmitted with data signals for channel sounding. The pilot signal does not degrade the receiver bit error rate (BER) performance because the receiver estimates the pilot signal and subtracts the estimated pilot signal from the received signal before data detection. A spreading code matched filter, a channel matched filter, and a sounding receiver
