Abstract
Official abstract text for this publication.
A communication device is configured to encode and/or decode low density parity check (LDPC) coded signals. Such LDPC coded signals are characterized by LDPC matrices having a particular form. An LDPC matrix may be partitioned into a left hand side matrix and the right hand side matrix. The right hand side matrix can be lower triangular such that all of the sub-matrices therein are all-zero-valued sub-matrices (e.g., all of the elements within an all-zero-valued sub-matrix have the value of “0”) except for those sub-matrices located on a main diagonal of the right hand side matrix and another diagonal that is adjacently located to the left of the main diagonal. A device may be configured to employ different LDPC codes having different LDPC matrices for different LDPC coded signals. The different LDPC matrices may be based generally on a common form (e.g., with a right hand side matrix as described above).
First claim
Opening claim text (preview).
What is claimed is: 1. A communication device comprising: a communication interface; and a processor, at least one of the processor or the communication interface configured to: encode information bits using a low density parity check (LDPC) code to generate coded bits, wherein the LDPC code is characterized by an LDPC matrix that includes a plurality of sub-matrices arranged in a left hand side matrix and a right hand side matrix, wherein the right hand side matrix is lower tr…
