    Abstract: A symbol detector with a sphere decoding method implemented therein. A baseband signal is received to determine a maximum likelihood solution using the sphere decoding algorithm. A QR decomposer performs a QR decomposition process on a channel response matrix to generate a Q matrix and an R matrix. A matrix transformer generates an inner product matrix of the Q matrix and the received signal. A scheduler reorganizes a search tree, and takes a search mission apart into a plurality of independent branch missions, wherein the search tree defines a full search depth Nfull. A plurality of Euclidean distance calculators are controlled by the scheduler to operate in parallel, wherein each has a plurality of calculation units cascaded in a pipeline structure to search for the maximum likelihood solution based on the R matrix and the inner product matrix.

    Abstract: A system and method for inter-cell interference avoidance. A base station is configured to perform interference avoidance. The base station receives feedback information from either a second base station or a subscriber station served by the second base station. The base station selects a codebook vectors or matrices for transmission to subscriber stations based, at least in part, on a portion of the feedback information. The base station is further configured to select which subscriber stations will participate in interference avoidance calculations.

    Abstract: An apparatus and associated methodology providing read channel circuitry having a signal equalizer that sends an equalized signal to a bit detector. The read channel circuitry is capable of sampling values of the equalized signal to identify a bit transition from among a predefined plurality of different bit transitions. The apparatus may have channel optimization (CO) logic that, based on the input signal and the sampling of the equalized signal, defines first values for a programmable parameter of the bit detector that substantially maximizes vector separations among vectors of waveform target samples corresponding to the predefined plurality of different bit transitions, while the CO logic also defines second values for a programmable parameter of the equalizer that substantially minimizes the mean squared separation of the equalized signal segment for each bit transition from the waveform target corresponding to that bit transition.

    Abstract: An equalizer for equalizing a composite signal originating from a given number of simultaneous data streams able to be received over a communication channel, on a given number of antennas, at one or more radio units, in a wireless communication system. The equalizer performs matrix operations when the number of receiving antennas associated with the composite signal is lower than the number of antennas supported by the equalizer. The channel matrix and the signal and interference covariance matrices are manipulated. The antenna dimension is increased, padding is then added and the transmitted signal vector is finally determined based on the altered matrices.A baseband processing unit, a method and a computer program are also claimed.
