This work aims at evaluating the performance of a Direct Sequence Spread-Spectrum (DS-SS) system over a 60 GHz real indoor channel characterized by the presence of severe multipath. The channel has been described by 1680 impulse response data calculated by means of a 3-D ray-tracing program. Both multipath components with delays shorter and longer than the chip time have been examined, and a special emphasis has been placed onto the study of the multipath effects on the DLL tracking circuit. The obtained results show the spatial distribution of the effective received energy per bit at the data demodulator input and provide some useful indications about the design criteria for an indoor wireless wideband local area network at EHF.

Abstract
This work aims at evaluating the performance of a Direct Sequence Spread-Spectrum (DS-SS) system over a 60 GHz real indoor channel characterized by the presence of severe multipath. The channel has been described by 1680 impulse response data calculated by means of a 3-D ray-tracing program. Both multipath components with delays shorter and longer than the chip time have been examined, and a special emphasis has been placed onto the study of the multipath effects on the DLL tracking circuit. The obtained results show the spatial distribution of the effective received energy per bit at the data demodulator input and provide some useful indications about the design criteria for an indoor wireless wideband local area network at EHF.
