b radio receiver homu00f3dino quadrature low if d .A receiver demodulates signals of single edge homu00f3dino square containing portions by use of a spectral null intermediate frequ00b3u00eancia extremely low that normally would create self I.Nterferu00eancia substantial. This is accomplished by placing carefully the spectral null portions on the critical sections of the spectrum of the signal, ensuring that the self interference is minimized.As an example, a signal of CDMA of sequ00b3u00eancia directly, which was built with no more than half of Walsh functions available.It is desmodulado directly by placing an intermediate frequ00b3u00eancia such that portions of spectral null in CDMA signal overlap if spectral peaks in the desired signal.Thus eliminating the self interference. This homu00f3dino receiver end only can be implemented using components integrated or discrete components.
