Abstract :
A novel multipath diversity scheme used in TDD-CDMA systems is presented. A FIR filter is added in the transmitter, while a RAKE combiner is used in the receiver. The optimum FIR filter problem may be viewed as an eigenvalue problem. The multiple antennas system is also analyzed. Results show that the signal-to-noise ratio (SNR) can be further improved when the FIR RAKE system is combined with an antenna array
