Various embodiments are described to select or adjust transmission parameters in a multicarrier system wherein one or more transmission parameters are selected to substantially match a block of data to a group of multicarrier symbols.

Technique to select transmission parameters

Embodiments of the present invention provide methods and apparatus for wireless communication using codeword with high-rate codes. Other embodiments may be described and claimed.

Wireless communication using codeword encoded with high-rate code

A system, apparatus, method, and article including a decoder having multiple connections defined between multiple check nodes and multiple symbol nodes. The connections between the multiple check nodes and the multiple symbol nodes are reconfigurable to enable the decoder to decode multiple codes. Other embodiments are described and claimed. The system further includes an antenna.

Techniques for reconfigurable decoder for a wireless system

An embodiment of the present invention provides an apparatus, comprising a transceiver capable of a unified quasi-cyclic low-density parity-check structure for variable code rates and sizes using a unified base matrix definition. This base matrix definition may be a concatenation of multiple square matrices=()and the base matrix for rate (r&#x2212;1)/r may be=()

Apparatus and method capable of a unified quasi-cyclic low-density parity-check structure for variable code rates and sizes

A low density parity check (LDPC) code is used within a wireless apparatus to perform forward error correction (FEC) coding. In at least embodiment of the invention, a (2000, 1600) bit-length LDPC code is used.

Method and apparatus for implementing a low density parity check code in a wireless system

A method and apparatus for encoding/decoding information using low density parity check (LDPC) codewords of varying lengths. In one implementation, an encoder/decoder uses a parity check matrix having a size that corresponds to a length of information for each codeword. In one example, the size of the parity check matrix may be retrieved from multiple stored matrices having different sizes. In other examples, a mother code matrix may be dynamically adjusted by puncturing parity bits and/or deleting information bits. Other inventive embodiments and adaptations are also disclosed.
