Abstract

The paper deals with the realization of a new instrument for the qualification of third-generation (3G) mobile telecommunication systems. It is based on the parallel computing of a time-frequency representation called smoothed pseudo-Wigner-Ville distribution (SPWVD) on a multiple digital signal processor architecture. The SPWVD allows the performance of signal analysis simultaneously in both the time and frequency domain. The hardware and software implementations of the instrument prototype are presented and discussed. Then, the first validation results, obtained on wide-band code-division-multiplexing access (W-CDMA) signals compliant with the 3rd Generation Partnership Program (3GPP) standard, are reported.
