Abstract
A hardware efficient implementation of a threshold modified attenuated min-sum algorithm (TAMSA') and a threshold modified offset min-sum algorithm ('TOMSA') that improve the performance of a low density parity-check ('LDPC”) decoder by reducing the bit error rate (“BER”) compared to the conventional attenuated min-sum algorithm (“AMSA”), offset min-sum algorithm (“OMSA”), and the min-sum algorithm (“MSA”). Embodiments of the present invention preferably use circuit optimization techniques, including a parallel computing structure and lookup tables, and a field-programmable gate array (“FPGA”) or application specific integrated circuit (“ASIC”) implementation.
