Design and Implementation of 4-QAM Transceiver on FPGA using MATLAB/SIMULINK Model

Abstract

4-QAM Modulation is exclusively used in 4G and 5G transceivers where the received power is low. This paper discusses the such type of modulation scheme with full implementation on FPGA. The design of the 4-QAM transceiver circuit is done using MATLAB/Simulink as a Model and then subsequently generating the VHDL codes for this model. FEC (Forward Error Correction) is also employed in the design. This circuit is implemented on ZEDBOARD which uses Zync-7000 series FPGAs. It has an SoC with Zync7000 and an ARM processor. The codes for the model have been generated automatically with VHDL codes for the FPGA section and C-codes for the ARM processor. The model-based design saves a lot of time in coding, debugging, and testing the transceiver.
