    摘要： The present invention provides a method and an apparatus for communicating data over a network between a communication node, for example, an access point having a first and a second antenna and a first and a second mobile station. The method comprises weighting a first data at the access point to transmit the first data using the first and second antennas so that the first mobile station only receives the first data and weighting a second data at the access point to transmit the second data using the first and second antennas so that the second mobile station only receives the second data. A space division multiple access (SDMA) module may cause a transmission protocol to transmit the first data to the first mobile station on the downlink and transmit the second data to the second mobile station in parallel to the transmission of the first data on the downlink. In a telecommunication system, this substantially simultaneous transmission of the first and second data using a similar carrier frequency in a radio frequency communication over a wireless local area network (WLAN) may increase throughput of a downlink, for example, by a factor nominally equal to the number of antennas at an access point.

    摘要： The present invention relates to multiple-antenna interference cancellation, more particularly to a receiver for wirelessly transmitted digital data bursts and a method for multiple-antenna interference cancellation for wirelessly received digital data bursts. The invention is particular useful for multiple-antenna interference cancellation in unsynchronized backhaul and/or cellular WIMAX-based networks. A receiver (10) for wirelessly transmitted digital data bursts including training data for wireless channel estimation is provided. The receiver comprises: a plurality of antenna elements for receiving input data; a first estimator (13, 14, 15) for estimating a first set of antenna weights for the antenna elements from first training data; a second estimator (13, 14, 15) for estimating a second set of antenna weights for the antenna elements from second training data; a first space-frequency filter (17, 18, 19) for providing a first symbol candidate for the input data based on the first set of antenna weights; a second space-frequency filter (17, 18, 19) for providing a second symbol candidate for the input data based on the second set of antenna weights; and a selector (20) for selecting, as data symbol estimate, the first symbol candidate or the second symbol candidate.

    摘要： In a radio telecommunications system such as GSM or EDGE, at each timeslot 10 a small number of information symbols in narrow bands (24, 26) of the data payloads (20,22) adjacent each tail (16, 18) of the timeslot are used as training-like symbols; for each burst, the end of the timeslot more affected by asynchronous CCI is sensed, and the training-like symbols at that end are processed, together with conventional midamble (14) training symbols and tails symbols (16,18), by a CCI rejection algorithm.

    摘要： A receiver of digital data bursts is provided comprising an antenna array (A), a first space time filter (26) having filter coefficients initialised by estimation over just training data in a received burst (LST) and providing symbol estimates and a second space time filter (28) having filter coefficients initialised by estimation over the received burst (LSB) and providing symbol estimates. In use at least one pass to determine a symbol estimate in the received burst is undertaken by each space time filter and a selector (24) operates to determine which of the first and second filters provides the symbol estimate closer to an expected value.

    摘要： A mobile telephone system includes a base station which establishes a link with a selected mobile station. The received signal from the mobile station will include a noise component as well as a possible interference component from another mobile station operating at the same frequency in another cell.
    The base station has a trellis based equalisation system which operates on the assumption that the received signal includes components which have a predominantly Gaussian characteristic. A switch controller determines when the interference component (which is non-gaussian) in the received signal becomes a dominant component and operates to switch a spatio-temporal filter into the circuit instead of the trellis based equalisation system, to improve the bit error rate performance.
