ABSTRACT:
Apparatus and method for transmitting a digitized wideband signal robust to multipath degradation and intersymbol interference within a predetermined broadcast band. A basis set of wideband mutually orthogonal pseudorandom basis signal waveforms of substantially equal length and having predetermined autocorrelation values and a predetermined spectral shape are generated. The length of the waveforms in the set represents a baud. The wideband waveforms of the basis set are data modulated so as to define digital data. The basis set substantially maintains the predetermined spectral shape during the modulation.
