Abstract:We have proposed a digital-to-radio (DIR) converter that can directly change a digital signal generated by a logic circuit into a radio signal. This D/R converter enables an F W circuit and an antenna to be composed of one simple device, and the radio can be directly controlled by software; this is the essence of software radio. The proposed converter is therefore applicable to an adaptive radio terminal and an adaptive-array-antenna system .We developed a new algorithm that enables the DIR converter to conver… Show more
