Software defined radio (SDR) seems to be a solution for communications for rapid changes in the communication standards. Detector is the most important component of radio receiver. This paper describes the implementation of QAM-4 transceiver using very simple sampled matched filter detection technique. The advantage of using sampled matched filter is maximizing the signal-to-noise ratio (SNR) at the output of the matched filter. The Transceiver also uses Forward Error Correction (FEC) in the form of Reed-Solomon (7, 3) coding and decoding. This design is tested using a model based development platform for Software Defined Radio. The whole system consists of a Front-End or DSP model and a Back-End or FPGA model. FPGAs are chosen due to their high re-configurability and design flexibility when compared with Digital Signal Processors. Because of this the complete base-band processing of the transceiver is performed at the FPGA model. The coding for the front end is generated in C-language whereas the coding for the Back-End model is generated in VHDL.
