摘要： Header encoding for SC and/or OFDM signaling using shortening, puncturing, and/or repetition in accordance with encoding header information within a frame to be transmitted via a communication channel employs different respective puncturing patterns as applied to different portions thereof. For example, a first puncturing pattern is applied to a first portion of the frame, and a second puncturing pattern is applied to a second portion of the frame (the second portion may be a repeated version of the first portion). Shortening (e.g., by padding 0-valued bits thereto) may be made to header information bits before they undergo encoding (e.g., in an LDPC encoder). One or both of the information bits and parity/redundancy bits output from the encoder undergo selective puncturing. Moreover, one or both of the information bits and parity/redundancy bits output from the encoder may be repeated/spread before undergoing selective puncturing to generate a header.

摘要： A method for generating a preamble of an Orthogonal Frequency Division Multiplexed (OFDM) data frame for a multiple input multiple output (MIMO) wireless communication includes determining at least one system condition preamble format parameter. When the system condition preamble format parameter satisfies a first preamble format parameter a preamble having a first preamble format is formed. When the system condition preamble format parameter satisfies a second preamble format parameter, a preamble having a second preamble format is formed. Further, when the system condition preamble format parameter satisfies a third preamble format parameter, a preamble having a third preamble format is formed. The first, second, and third preamble formats differ based upon their lengths, fields, and modulation formats of a high throughput signal field.

A wireless receiver may determine whether a received multimedia data stream comprises video content and may select a redundancy-based decoder when video content is detected. The wireless receiver may be a WLAN receiver or a cellular receiver. Video content may be indicated by at least one flag in a preamble or a reserved field of the received multimedia data. The redundancy-based decoder may be a Viterbi decoder. The wireless receiver may enable a standard Viterbi decoder to decode portions of the multimedia data that do not comprise video content.

摘要： Aspects of a method and system for redundancy-based decoding of voice content in a wireless local area network (WLAN) system are provided. A WLAN receiver may determine whether a decoded portion of a received packet comprises voice content and may select a redundancy-based decoder to decode a remaining portion of the packet when voice content is detected. The redundancy-based decoder may be a Viterbi decoder. The redundancy-based decoder may be selected to decode a determined number of subsequent packets or to decode subsequent packets for a determined amount of time. After decoding the remaining portion of the packet and any subsequent packets, the WLAN receiver may select a standard Viterbi decoder to decode additional received packets. The WLAN receiver may generate at least one signal to select the redundancy-based decoder and the standard Viterbi decoder.
