    摘要： A communication system includes a transmitter that encodes binary bits of each of a plurality of data streams into a plurality of symbols and converts the plurality of symbols into a plurality of output signals, respectively corresponding to a plurality of channels, the converting based on a transmission rule defined by a first matrix; and a receiver that combines the plurality of output signals, received through the plurality of channels, the combining based on a reception rule defined by a second matrix, the combining restoring the plurality of symbols, and the receiver decodes the plurality of symbols into the binary bits. The first matrix and the second matrix are determined based on a third matrix that models a crosstalk effect between adjacent channels from among the plurality of channels, to reduce the crosstalk effect.

    摘要： An apparatus and digital signal processing means are disclosed for excision of co-channel interference from signals received in crowded or hostile environments using spatial/polarization diverse arrays, which reliably and rapidly identifies communication signals with transmitted features that are self-coherent over known framing intervals due to known attributes of the communication network, and exploits those features to develop diversity combining weights that substantively excise that co-channel interference from those communication signals, based on differing diversity signature, timing offset, and carrier offset between the network signals and the co-channel interferers. In one embodiment, the co-channel interference excision is performed in an appliqué that can be implemented without coordination with a network transceiver.

    摘要： Methods and systems are described for receiving symbols of a codeword via wires of a multi-wire bus, the codeword representing an aggregate sum of a plurality of sub-channel constituent codewords, each sub-channel constituent codeword representing a weight applied to an associated sub-channel vector of a plurality of sub-channel vectors of an orthogonal matrix, generating a plurality of comparator outputs using a plurality of common-mode resistant multi-input comparators (MICs), each common-mode resistant MIC having a set of input coefficients representing a corresponding sub-channel vector of the plurality of sub-channel vectors, each sub-channel vector (i) mutually orthogonal and (ii) orthogonal to a common-mode sub-channel vector, outputting a set of forward-channel output bits formed based on the plurality of comparator outputs, obtaining a sequence of reverse-channel bits, and transmitting the sequence of reverse-channel bits by sequentially transmitting common-mode codewords over the wires of the multi-wire bus.
