    摘要: Beamforming is provided for a wireless MIMO device by using antenna puncturing to reduce the number of transmit antennas that are used to transmit data for certain subcarriers. In a conventional approach, if N spatial streams are being used to provide spatial multiplexing, then N transmit antennas would be used to transmit for each subcarrier. In at least one embodiment of the invention, enhancements in channel capacity are achieved by using less than N transmit antennas for one or more subcarriers.

    摘要: LDPC (Low Density Parity Check) codes with corresponding parity check matrices selectively constructed with CSI (Cyclic Shifted Identity) and null sub-matrices. An LDPC matrix corresponding to an LDPC code is employed within a communication device to encode and/or decode coded signals for use in any of a number of communication systems. The LDPC matrix is composed of a number of sub-matrices and may be partitioned into a left hand side matrix and a right hand side matrix. The right hand side matrix may include two sub-matrix diagonals therein that are composed entirely of CSI (Cyclic Shifted Identity) sub-matrices; one of these two sub-matrix diagonals is located on the center sub-matrix diagonal and the other is located just to the left thereof. All other sub-matrices of the right hand side matrix may be null sub-matrices (i.e., all elements therein are values of zero “0”).

    摘要: The invention relates to a method for configuring a telecommunication system comprising at least one sending entity and one receiving entity between which the same link transmits several transport channels with different qualities of service. The sending entity matches the rate between the different coded transport channels with separate qualities of service, and the different coded transport channels are then multiplexed.

    摘要: Aspects of a method and system for utilizing Givens rotation expressions for asymmetric beamforming matrices in explicit feedback information are presented. In one aspect of the invention, Givens matrices may be utilized to reduce a quantity of information communicated in explicit feedback information via an uplink RF channel. The explicit feedback information may include specifications for a feedback beamforming matrix that may be utilized when transmitting signals via a corresponding downlink RF channel. The feedback beamforming matrix may represent a rotated version of an un-rotated matrix. The Givens matrices may be utilized to apply one or more Givens rotations to un-rotated matrix. The feedback beamforming matrix may be computed based on a matrix product of a plurality of Givens matrices. The feedback beamforming matrix may be encoded utilizing fewer bits than may be required to encode the un-rotated matrix.

    摘要: In a communication device that is operative to perform decoding, a log-likelihood ratio (LLR) circuitry operates to calculate LLRs corresponding to every bit location within a received bit sequence. This received bit sequence may include a header and a data portion (both of which may be included within a frame that also includes a preamble). The header is composed of information bits, a duplicate of those information bits (such as may be generated in accordance with repetition encoding), and redundancy bits. The header includes information corresponding to frame or data including frame length, a code type by which the data are encoded, a code rate by which the data are encoded, and a modulation by which symbols of the data are modulated. Once the header has been decoded, then the data corresponding thereto is decoded by a block decoder circuitry to make estimates of that data.
