Latest Patents
One of his latest patents is a threshold-based min-sum algorithm designed to lower the error floors of quantized low-density parity-check decoders. This modified version of the min-sum algorithm (MSA) aims to improve the error floor performance of quantized LDPC decoders. The invention introduces a threshold attenuated min-sum algorithm (TAMSA) and/or a threshold offset min-sum algorithm (TOMSA). These algorithms selectively attenuate or offset a check node log-likelihood ratio (LLR) when the check node receives any variable node LLR with a magnitude below a predetermined threshold. This allows the check node LLR to reach the maximum quantizer level if all variable node LLRs received have magnitudes greater than the threshold. The embodiments of this invention can yield desirable results even without knowledge of the location, type, or multiplicity of such objects and can be implemented with only minor modifications to existing decoder hardware.
