Abstract :
A wireless communications system with a transmission speed of 18 Mbit/s using the 2.4 GHz ISM band is presented. This system employs the "carrier frequency offset-spread spectrum (CFO-SS)" scheme and the "dual-polarization staggered transmission (DPST)" scheme. The proposed combined scheme has a high immunity against multipath and enables us to provide a long range communication link with high transmission. The detailed principle of CFO-SS and DPST schemes, together with the specifications and structure of the 18 Mbit/s CFO-SS system (CFO-SS18A) are presented. Results of indoor test obtained by CFO-SS18A are also presented to evaluate the feasibility of the proposed system.
