Abstract

Due to the need for spectrally efficient systems for wireless communication, many research activities have been carried out in the area of spread-spectrum techniques. Multi-carrier spread-spectrum (MC-SS) is a new modulation technique with better spectral properties than direct-sequence spread-spectrum (DS-SS). In this paper, a new MC-SS system is introduced. A customized surface acoustic wave (SAW) filter has been designed as a fast analog correlator. Furthermore, a demonstrator testbed has been developed for the 2.4 GHz industrial, scientific and medical (ISM) band and first measurements of the intermediate frequency (IF) and baseband correlation are being presented
