    Abstract

    In this paper, a new software defined radio platform with direct conversion is introduced. The platform is named SOPRANO, which stands for Software Programmable and Hardware Reconfigurable Architecture for Network. Main features of SOPRANO include a high-level design methodology for digital circuits, direct conversion based on six-port technology, and novel digital signal processing algorithms for multi-band and multi-mode operation. The first prototype of the SOPRANO platform has been built and was able to receive M-ary PSK (Phase Shift Keying) and QAM (Quadrature Amplitude Modulation) signals, with two different carrier frequencies at 2.45 GHz and 5.25 GHz, by changing signal-processing software.
