Title:
RECEIVER WITH DIGITAL PROCESSING OF A PHASE-SPLITTED INPUT SIGNAL
Document Type and Number:
WIPO Patent Application WO1997032391
Kind Code:
A3
Abstract:
In a receiver, both an A/D conversion (ADC) and a phase-spit (PSF) is carried out on an input signal (R) to obtain a pair of digital signals (Xd, Yd) which are mutually phase shifted. The pair of digital signals (Xd, Yd) is processed (VSP) as a vectorial signal with a frequency-characteristic which is asymmetrical with respect to zero frequency. In order to make the receiver better suited for relatively low A/D conversion sampling frequencies (Fs), the phase-split (PSF) is carried out prior to the A/D conversion (ADC). 00000
