1. A reception controller for processing data items received over a wireless link connecting a central terminal and a subscriber terminal of a wireless telecommunications system, a single frequency channel being employed for transmitting data items pertaining to a plurality of wireless links, and ‘

  • m’

    orthogonal channels being provided within the single frequency channel, the receiver controller comprising;

    an orthogonal code generator for providing an orthogonal code from a set of ‘

    m’

    orthogonal codes used to create said ‘

    m’

    orthogonal channels within the single frequency channel;

    a first decoder for applying, to signals received on the single frequency channel, the orthogonal code provided by the orthogonal code generator, in order to isolate data items transmitted within the corresponding orthogonal channel; and

    a TDM decoder arranged to extract a data item from a predetermined time slot within said orthogonal channel, a plurality of data items relating to different wireless links being transmitted within the same orthogonal channel during a predetermined frame period.
