The revolution of modern radio communication application such as radar, electronic warfare and signal intelligence using SDR technology has open an interest among researchers to adopt the technology in wireless communication system. This paper is focused on mechanisms and methodology to implement a low complexity SDR transceiver using Simulink, Matlab and Xilinx for FPGA environment. In this design, a spectrum frequency between 5 MHz to 20 MHz is sampled using QPSK modulation technique to achieve encoding and decoding of IF signal. The mechanisms and methodology of proposed transceiver design would help in SDR designing by providing a fast way altering a system with low complexity. It also opens the possibility of integrating cognitive radio aspect into wireless networks such as 3G and 4G in the future.
