Abstract
In this paper a multi-coded variable spreading gain (MC-VSG) CDMA system employing a binary transmission of MC signals by introducing a level clipper termed MC-VSG BNet system, is proposed for the candidate of wireless personal area network (WPAN) and 3G cellular applications. With an emphasis on the MC-VSG BNet physical layer we address the concise specification of the MC-VSG BNet system including the spreading code, level clipping, modulation, coding, frame format, and its applications. From the receiver performance based on simulation results, in addition to simple receiver structure, an acceptable performance degradation of the MC-VSG BNet system over the existing DS/CDMA system is observed, while guaranteeing a high bit rate transmission.
