Abstract
In wireless communication, the code parameters should have great flexibility to adapt to varying channel conditions. Hence, there is a need for configurable decoders capable of meeting various service requirements and interference conditions. Therefore, a reconfigurable LDPC decoder has been proposed to support multiple code lengths (19 different code lengths) with code rate 1/2 of IEEE 802.16e WiMAX standard LDPC codes. This paper proposes the architecture of a reconfigurable LDPC decoder with parallel factor equal to 4. The reconfiguration parameters are stored in a ROM to configure the architecture to support different code lengths.
