摘要： Embodiments of an OFDM transmitter and method of reducing the effects of interference on subcarriers in an OFDM system by symbol loading are disclosed herein. A linear transformation is performed on a group of two or more input data symbols to generate a corresponding two or more output data symbols. Each of the output data symbols has an increased number of constellation points and are configured for transmission within one of the different signal dimensions using two or more antennas. Each of the two or more output data symbols carry the information of each of the input data symbols of the group. This coding together of input data symbols that are mapped to different signal dimensions may provide improved reliability against fading and severe interference. The different signal dimensions may comprise a frequency, a time and/or a space dimension.

摘要： Bit probability estimates generated by a turbo decoder are employed to weight the bits of a received packet before combining the received packet with a redundant packet. Bits are individually weighted by the corresponding bit probability estimate and all bits within the received packet are weighted by a block confidence estimate generated from the cumulative bit probability estimates for the received packet. Weighted packet bits are combined within either weighted packet bits for the redundant packet or unweighted received bits for the redundant packet. The bits are combined by adding counterpart weighted (or weighted and unweighted) systematic and parity bit values within the two packets while inserting disjoint parity bit values within the combined result. Decoding performance for incremental redundancy systems utilizing turbo decoding is improved.

摘要： A method and an apparatus for decoding trellis coded direct sequence spread spectrum communication signals are provided. A transmitted QPSK signal is received. Binary phase-shift keyed (BPSK) despreading is performed on the QPSK signal. The BPSK despreading comprises correlating the in-phase and the quadrature components of the received QPSK signal with independent PN sequences for the each of the in-phase and the quadrature components. The despread signal is then demultiplexed, and the pilot signal and the BPSK data signal are recovered. The recovered pilot signal is used to provide a channel phase estimate and a channel magnitude estimate. The recovered BPSK data signal is demodulated, despread, and decoded. The despreading and decoding comprises determining a number of cross-correlation terms of the received signal using a number of transmitted biorthogonal Walsh sequences. The cross-correlation terms are used as the branch metrics in a maximum likelihood decoding algorithm. The branch metrics may be computed with a Fast Walsh Transform scaled in response to the channel phase estimate from the recovered pilot signal. The maximum likelihood decoding algorithm may be a Viterbi algorithm in which the optimum path is the path with the maximum accumulated branch metric. The decoding algorithm recovers and outputs a transmitted data bit sequence.

摘要： Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

摘要： Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, super-blocks, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.
