Affine precoders for reliable communications

  title={Affine precoders for reliable communications},
  author={Jonathan H. Manton and Iven M. Y. Mareels and Yingbo Hua},
It is known that precoding a signal prior to its transmission through an unknown finite impulse response channel facilitates the equalisation of the channel. Moreover, since linear precoders spread the spectrum, the equalisation process mitigates the effects of channel spectral nulls caused by frequency selective fading. This paper argues that certain affine precoders are more efficient than linear precoders. Here, the efficiency of a precoder is a measure of its ability to enable the receiver… CONTINUE READING
