Patent abstract
A first device is described. The first device may include a linear transformation circuit to implement multiplication by a matrix D. The linear transformation circuit may have an input to receive a vector having N digital values and an output to output N first output signals, a sign-adjustment circuit to adjust signs of a subset including at least M of the N first output signals in accordance with a set of coefficients H, and a conversion (DAC) circuit coupled to the sign-adjustment circuit. Outputs from the DAC circuit may be summed to produce an output.
