摘要

In this work, we propose a design and FPGA (Field Programmable Gate Arrays) implementation of three parallel architectures for majority logic decoder of low complexity for high data rate applications. These architectures are hard decision decoder architecture (Hard in - Hard out (HIHO)), the SIHO threshold decoding (Soft in – Hard out) and the SISO threshold decoding (Soft in – Soft out). The chosen code is the Difference Set Cyclic DSC code. The VHDL (Very high speed integrated circuit Hardware Description Language) design and the synthesis of such architectures show that such decoders can achieve high data rate with low complexity. In our case, the iterative decoder associated to the fully parallel SISO threshold decoders allows achieving high data rates, 2 clock cycles for two iterations with a complexity of 7350LEs.
