Resumen:
In this paper a low complexity logarithmicdecoder for a LDPC code is presented. Theperformance of this decoding algorithm is similar tothe original decoding algorithm´s, introduced by D.J. C. MacKay and R. M. Neal. It is a simplified algorithmthat can be easily implemented on programmablelogic technology such as FPGA devices becauseof its use of only additions and subtractions,avoiding the use of quotients and products, and offloat point arithmetic. The algorithm yields a verylow complexity programmable logic implementationof a LDPC decoder with an excellent BER performance.
