    摘要： A signal processing apparatus comprises a plurality of receiving elements, weighting means, and decoding means. Each of the receiving elements has respective weighting means associated therewith at the decoding means, and is arranged to receive a plurality of signals transmitted from a plurality of transmitters. The weighting means are arranged to apply a complex weighting function to each of a number of the signals received by the receiving elements at a given frequency in order to null the number of signals. The decoding means are arranged to determine a symbol or codeword associated with a non-nulled signal and to incorporate the symbol or codeword in the determination of at least one further symbol or codeword.

    摘要： This invention relates to a method and system of transmitting video data and multimedia data to a plurality of client radio receivers over an air interface using an adaptive encoding/transcoding scheme and updating the adaptive encoding/transcoding scheme in dependence upon received feedback data. A system and method is also described that includes estimating channel states and distortion levels for a plurality of transmission modes, then selecting that transmission mode for subsequent data transmission that has the lowest distortion level. Control data items can also be extracted from the first data stream to produce a multimedia data stream and a control data stream and the multimedia data stream is transmitted over a first channel; and the control data stream is transmitted over a second channel. The received data stream may be put into a plurality of multimedia slices having a predetermined slice size; and encoded into first data packets of a first predetermined size; which in turn are divided into respective integral second data packets of a second predetermined size and which are aggregated into a stream of third data packets of a third predetermined size.
