Title:
SYSTEMS AND METHODS FOR A LOG-LIKELIHOOD RATIO BASED DYNAMIC PRE-PROCESSING SELECTION SCHEME IN A LOW-DENSITY PARITY-CHECK DECODER
Document Type and Number:
WIPO Patent Application WO/2018/069767
Kind Code:
A8
Abstract:
Embodiments described herein provide a system for dynamically selecting a pre-processing scheme for an LDPC decoder (106). The system includes a receiver configured to detect transmission of a first data packet and receive a first set of data bits corresponding to a first portion of the first data packet. The system further includes a histogram generator (103) configured to calculate log-likelihood ratios for each data bit from the first set of data bits, and generate a histogram based on the calculated log-likelihood ratios. The receiver is configured to continue receiving a second set of data bits corresponding to a second portion of the first data packet. The system further includes a selector (104) configured to activate or inactivate a log-likelihood ratio pre-processing scheme (105) on the received second set of data bits based on characteristics of the histogram.
