Abstract

According to the baseband signal model and features in Code Division Multiple Access(CDMA)communication systems

the paper analyzes SNR estimation techniques for Quadrature Phase-Shift Keying (QPSK)modulations and proposes a novel SIR estimation technique for CDMA.The results of computer simulation show that the estimation creditability using this technique is higher than others in low SIR.
