| Abstract: | In this paper,FPGA implementation of a 16QAM receiver demodulation chip used for microwave transmission device has been presented.The receiver chip includes timing recovery,carrier recovery and blind adaptive decision feed back equalizer(DFE).Constant modulus algorithm is used for the equalizer.The receiver chip supports high data rate up to 25Mbaud symbol rate.The receiver is implemented on EP1C12Q240C8(ALTERA) which will be used on the microwave transmission device soon. |
