ZigBee Based Wireless Data Transmission with LDPC codes using FPGA

摘要

Due to advancements in wireless communication, data transmission through noisy channel demands some efficient coding techniques. A Low Density Parity Check (LDPC) code performs dependable exchange of data over a noisy channel through long distances. LDPC code is basically a linear forward error correcting code. Error detection and correction in the decoder without any additional circuitry is the key component. In this paper 3 bit LDPC code encoder and decoder is designed in Verilog HDL synthesized in Xilinx and implemented on Spartan3E FPGA. ZigBee is interfaced with FPGA to transmit data in wireless between transmitter and receiver through media.
