The method continues by determining a number of reception antennas for the asymmetrical MIMO wireless communication. The method continues by, when the number of transmission antennas exceeds the number of reception antennas, using spatial time block coding for the asymmetrical MIMO wireless communication. The method continues by, when the number of transmission antennas does not exceed the number of reception antennas, using spatial multiplexing for the asymmetrical MIMO wireless communication.

Abstract: A receiver receives chip-level data items via a plurality of individual distinct path signals in a signal cluster that is wirelessly received. Channel estimates and timing reference signals, and lock indications of valid components values in the channel estimates are generated utilizing the received chip-level data items. Rake receiver fingers are assigned to the received individual distinct path signals based on the generated channel estimates and timing reference signals, and/or the lock indications. Each of the received chip-level data items corresponds to one of the assigned rake receiver fingers. At least a portion of the received chip-level data items may be combined utilizing the assigned rake receiver fingers. The generated one or more combined chip-level data items may be despreaded to generate corresponding symbol-level data.

Abstract: 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.

Abstract: In a video system, a method and system for block noise reduction are provided. Edge parameters based on spatial variance may be determined to detect vertical edges that may result from block noise. These edge parameters may be determined serially. Once detected, pixels neighboring the vertical edges may be filtered and clamped to determine a vertical block noise reduction difference (BNR) parameter. Similarly, edge parameters based on spatial variance may be determined to detect horizontal edges that may result from block noise. These edge parameters may be determined serially. Once detected, pixels neighboring the horizontal edge may be filtered and clamped to determine a horizontal BNR difference parameter. The vertical and horizontal BNR difference parameters may be utilized to reduce block noise artifacts in the video image.

Abstract: Physical layer (PHY) sub-channel processing. A soft symbol decision stream is arranged into a number of sub-channels to reduce substantially the processing performed within a communication receiver on data that is not intended for that communication receiver.

Only the sub-channel that includes these soft symbol blocks, destined for this communication receiver, need be decoded. The soft symbol blocks not within the sub-channel may be discarded thereby recovering some of the processing capabilities of the communication receiver.
