Study on the SNR Gain of RAKE Demodulator

Abstract:

Classic RAKE demodulator(RAKEDE), multi-carrier coherent RAKEDE and RAKEDE with two antennas are given in the paper. According to those schemes provided, the G_SNR, which means the gain of signal to noise ratio (SNR), for those three kinds of RAKEDE is derived, and the closed form of the expression for G_SNR of those three kinds of RAKEDE is given in the paper. Comparing with those performance evaluation methods of RAKEDE existed, the method derived in this paper on the basis of diversity reception is more usable and easy to be accept.
