Abstract
Official abstract text for this publication.
A method for measuring a signal-to-noise ratio when decoding Low Density Parity Check (LDPC) codes is provided. The method includes receiving from an input of a demodulator an input code word with “strong” or “weak” solutions, decoding the input code word in a LDPC decoder using a predetermined dependence of a mean number of iterations on the signal-to-noise ratio, recording a number of iterations performed during the decoding of the input code word, averaging derived values of the number of iterations for a specified time interval, estimating a signal-to-noise ratio based on averaged derived values of the number of iterations and based on the predetermined dependence of the mean number of iterations on the signal-to-noise ratio, and generating an output decoded code word.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for measuring a signal-to-noise ratio when decoding Low Density Parity Check (LDPC) codes, the method comprising: receiving from an input of a demodulator an input code word; decoding the input code word in a LDPC decoder using a predetermined dependence of a mean number of iterations on the signal-to-noise ratio; recording a number of iterations performed during the decoding of the input code word; averaging derived values of the number…
