摘要： Systems and methods are provided that use LDPC codes to determine the locations of insertions or deletions within bit-strings of information transmitted through communication channels and which notify a LDPC decoder of the locations of the insertions or deletions prior to the start of the decoding process. The use of such systems and methods, according to this disclosure, may improve LDPC decoder performance by reducing errors cause by insertions and/or deletions. The use of such systems and methods, according to this disclosure, may also provide improved application performance and larger data transmission rates.

摘要： In one embodiment, the present invention includes an error correction method. The error correction method comprises receiving a digital signal and processing the digital signal to perform a first error correction. The first error correction includes a first correction for data insertions or deletions and a first correction of data errors to generate a reference signal. The reference signal corresponds to the digital signal having been corrected to a first correction accuracy. The digital signal and the reference signal may be processed to perform a second correction for data insertions or deletions to generate a synchronized signal. The second correction of the digital signal is based on the reference signal, and the correction accuracy of the second correction is more accurate than the first correction accuracy.
