1. A transform circuit, comprising:

  • a first circuit to map a set of N digital data symbols from N parallel data streams to N analog data symbols by generating N sets of first weighted sums of the N digital data symbols, each respective first weighted sum defined by a respective set of pre-determined first weighting values in a first matrix; and

    a second circuit to map the N analog data symbols to a sequence of N output signals over N time intervals, each of the N output signals corresponding to a respective second weighted sum of the N analog data symbols, each respective second weighted sum defined by a respective set of pre-determined second weighting values in a second matrix;

    wherein the first circuit and the second circuit together generate a pre-defined transform of the N digital data symbols.
