Abstract
The device and method provide precoding and symbol-rate transmitter spectral shaping of signals representative of digital information. The invention improves reliability of reception in the presence of non-Gaussian channel noise. The present invention also provides a flexible way of choosing between linear equalization, precoding without spectral shaping, and precoding with spectral shaping.
