摘要： A source node selects a plurality of transmitting nodes to cooperatively encode a set of original packets to transfer to a destination node. Encoding produces a plurality of coded packets and a corresponding code matrix of coefficients. The coded packets and the corresponding code matrix comprise a set of independent equations of independent variables in a system of linear equations, wherein the independent variables comprise the original packets. A destination node may select a set of receiving nodes to cooperatively receive the transmissions. The destination node collects the coded packets and code matrix from the receiving nodes, which provide a sufficient number of independent equations for decoding the original packets. Decoding comprises calculating a solution for the system of linear equations.

摘要： In a coordinated multipoint system, geographically distributed base transceiver stations employ overlapping coverage areas in a Radio Access Network (RAN) to serve multiple User Equipments (UEs). A fronthaul network communicatively couples the base transceiver stations to a central processor. The central processor comprises a cooperative multiple-input, multiple-output (MIMO) processor configured to select multiple antennas residing on multiple ones of the base transceiver stations to serve each of the UEs; compute baseband pre-coding weights for signals to be transmitted by the antennas, the baseband pre-coding weights computed from RAN channel state information between the antennas and the UEs; and coordinate transmissions of pre-coded signals from the antennas to exploit multipath in the RAN to coherently combine at each of the UEs. Since each UE can be provided with its own localized coherence zone, this enables the UEs to concurrently employ the same frequency spectrum.

摘要： A cooperative multi-user multiple input, multiple output (MIMO) system coordinates wireless client devices to provide cooperative uplink transmissions. A group of wireless client devices is selected based on their channel state information such that their uplink transmissions are uncorrelated. All of the client devices in the group transmit data on the same set of OFDM subcarriers. Channel state information is also communicated to at least one base transceiver along with the data. The channel state information may be measured by the wireless client devices, or the channel state information may be determined from pilot tones transmitted by the wireless client devices and received by at least one base transceiver. A cooperative-MIMO processing system communicatively coupled to at least one base transceiver processes the received uplink transmissions and the channel state information to separate received interfering signals via subspace de-multiplexing.

摘要： A cooperative multi-user multiple input, multiple output (MIMO) system coordinates spatially distributed transceiver stations for communicating with wireless client devices. The system comprises a network interface communicatively coupled to the transceiver stations via a backhaul network, which may comprise a wireless local area network. A MIMO processor pre-codes NR original data streams to generate NT subspace-coded data streams, wherein each subspace-coded data stream comprises a linear combination of at least some of the original data streams. NT may denote a number of transmitting antennas, and NR may denote a number of receiving antennas. A network controller conveys the subspace-coded data streams to the transceiver stations via the backhaul network and coordinates the simultaneous transmission of the subspace-coded data streams over wireless links to the wireless client devices. The pre-coding causes the transmissions to coherently combine at a first wireless client device to produce at least a first data stream while suppressing inter-user interference from at least a second data stream intended for at least a second wireless client device. The client devices and/or the transceiver stations may be selected based on channel state information and/or measured channel quality.

摘要： Systems, methods, and apparatuses for analyzing a wireless communication signal are provided. A set of linear operations is performed on a received signal vector, which comprises values of a transmitted signal received by a receiver. The set of linear operations is configured to produce an expanded matrix having multiple rows and multiple columns. The column values in each row of the base expanded matrix are summed to produce a processed signal vector. At least one signal parameter of the processed signal vector is measured to produce at least one signal parameter measurement, and based on the at least one signal parameter measurement, at least one column in the expanded matrix is updated to produce an updated expanded matrix.

摘要： A computer-implementable method employs radio signal metadata to train a cognitive learning and inference system to produce an inferred function, wherein the metadata comprises a syntactic structure of at least one radio communication protocol. The inferred function is used to map metadata of a detected radio signal to a cognitive profile of a transmitter of the detected radio signal. The mapping effects intelligent discrimination of the transmitter from at least one other transmitter through corroborative or negating evidentiary observation of properties associated with the metadata of the detected radio signal. A response to the transmitter is based upon the mapping.

摘要： A method for receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal transmitted by a user device in a wireless network comprises determining which subcarrier frequencies are allocated to the user device; converting the OFDM signal to a frequency-domain values corresponding to the subcarrier frequencies; and decoding the frequency-domain values to recover data symbols encoded by the user device on the subcarrier frequencies. The decoding employs codes that are inverse to, complex-conjugate of, or complementary to a set of complex-valued codes employed by the user device to shape the OFDM signal into a superposition of cyclic-shifted pulse waveforms, wherein each of the pulse waveforms has one of the data symbols modulated thereon.

摘要： An OFDM transmitter spreads original data symbols with a complex-valued spreading matrix derived from a discrete Fourier transform. Spread data symbols are mapped to OFDM subcarriers. Spreading and mapping are configured to produce a transmitted spread-OFDM signal with a low peak-to-average power ratio (PAPR) and orthogonal code spaces. In MIMO systems, the complex-valued spreading matrix can comprise a MIMO precoding matrix, and the code spaces can comprise MIMO subspaces. In Cooperative-MIMO, a combination of low code-space cross correlation and low PAPR can be achieved.
