Low power Transceiver Structure for Wireless and Mobile Systems Based SDR Technology Using MATLAB and System Generator

This paper presents the design and implementation of Software Defined Radio (SDR) transceiver based 16-QAM as one of the key techniques in structure of wireless and mobile communication system. The widely used of QAM in adaptive modulation due to efficient power and bandwidth force the researchers to found better and easy design by use the available software like MATLAB in order to advance the idea of software defined radio. The setting of parameter for random generator, QAM modulation and demodulation, AWGN wireless channel are provided. The Error rates of QAM system against the signal-to-noise ratio are used to evaluate the QAM system. The implementation results shows the system capability to transmitand receive intermediate frequency of 40 MHZ keeping the power under limited FPGA Slices and look up table (LUT).
