Rotating Polarization Wave Communication System using Software Defined Radio Controlled by Micro Processor

The prototype of Rotating Polarization Wave (RPW) radio is proposed. The prototype consists of two evaluation boards of commercial Radio Frequency (RF) chips, an evaluation platform of general-purpose microprocessor, and the 90-degree hybrid coupler. These boards are categorized into Software Defined Radio (SDR) that is performed by embedded C language programs. A RPW communication system using the proposed prototype radios achieves to enhance not only quality but also range of communication in various wireless environments by developing a novel embedded program on a free c programming language platform.
