Abstract
A novel methodology is proposed in this paper to design and implement an improved Digital Audio Broadcasting (DAB) channel codec that is based on Eureka-147 specifications including energy-dispersal, interleaving, concatenated Reed-Solomon and punctured convolutional coding techniques. Furthermore, by utilizing MATLAB/Simullink software, Xilinx System Generator, Xilinx Alliance tools, Xilinx XSE & ISE and Modelsim XE software, a transceiver platform is built-up to simulate and analyze the performance of the DAB channel codec based on FPGA hardware implementation. Rapid measurement of critical design considerations can be performed that include noise interference, multi-path fading, etc. Further, the proposed hardware platform can be used directly in practical DAB transmission.
