Development and Validation of an optimized syndromes block for reed solomon decoder

Reed Solomon decoder plays an indispensable role in many applications involving data transmission, storage and Video broadcasting DVB-T DVB-S2. In this work we propose a new optimized parallel syndrome block [67] for the RS code (15,11) used digital DVB-T. Therefore, proposed is compared to serial existing. On basis of technique architecture based on three syndromes developed. This reduces both energy consumption number iterations. The (15, 11) composed 255 symbols that are multiples 3. entered block. These decoding algorithms developed with existing algorithms, they evaluated through simulation using hardware description language VHDL, then implemented Xilinx Spartan type FPGA card XILINX software.
