| Abstract: | In order to improve the performance of demodulator for QPSK,a scheme of associated baseband processing demodulator with adaptive equalization is presented in this paper.The results obtained from theoretical analysis and computer simulations show that the demodulator has the significant advantage compared with those already used because of adaptive equalization and the simultaneous estimation of carrier phase and symbol timing, which compensate the defects of devices.Furthermore,the scheme allows an easy hardware implementation. |
