This paper deals with the design and realization of an Application Specific Integrated Circuit (ASIC) for fast Signal Recognition and Code Acquisition (SR/CA) in Direct-Sequence Spread-Spectrum Code Division Multiple Access (DS-SS-CDMA) receivers operating in a satellite or terrestrial radio network. The SR/CA problem is often the bottleneck of any DS-SS-CDMA system operating in spread-Aloha random access mode for the common access channel or when packet mode operation is envisaged. The single ASIC implementation provides a reliable, high-performance, low-cost, low-power consumption solution to such a problem. In particular, this paper explains how a parallel acquisition circuit can be effectively implemented on a single chip with a 1.0 μm CMOS (Complementary Metal Oxide Silicon) technology, complying with the specifications of the ESA (European Space Agency)/Inisel Ku-band CDMA VSAT (Very Small Aperture Terminal) system.

Abstract
This paper deals with the design and realization of an Application Specific Integrated Circuit (ASIC) for fast Signal Recognition and Code Acquisition (SR/CA) in Direct-Sequence Spread-Spectrum Code Division Multiple Access (DS-SS-CDMA) receivers operating in a satellite or terrestrial radio network. The SR/CA problem is often the bottleneck of any DS-SS-CDMA system operating in spread-Aloha random access mode for the common access channel or when packet mode operation is envisaged. The single ASIC implementation provides a reliable, high-performance, low-cost, low-power consumption solution to such a problem. In particular, this paper explains how a parallel acquisition circuit can be effectively implemented on a single chip with a 1.0 μm CMOS (Complementary Metal Oxide Silicon) technology, complying with the specifications of the ESA (European Space Agency)/Inisel Ku-band CDMA VSAT (Very Small Aperture Terminal) system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
