| Abstract: | Wishbone is one of System-on-Chip(SOC) bus standards which is used in sensor control system.In this paper,a reconfigurable low density parity check code(LDPC) encoder based on Wishbone standard is proposed,and it can be used in wireless communication of sensor network.The RU algorithm is applied to decreasing the encode complexity,and the pipeline structure is applied to designing the circuit.The encoder is in response to bus signal according to its working state.The decoders with a code rate of 1/2,and a m... |
