A software defined radio platform with direct conversion: SOPRANO
نویسندگان
چکیده
ilktract-In this paper, a new software defined radio plat-forim with multiport-based direct conversion is proposed, named SOPRANO (Software Programmable and Hardware Eeconfigurable Architecture for Eetwgrk). The main features of SOPRANO are a high-level design methodology for digital circuits, a new mixer-less direct conversion method, and software algorithms for multi-band and multi-mode operation. We built the first prototype SOPRANO 1.0, which wa13 able to receive PSK and QAM signals with two different carrier frequencies at 2.45GHz and 5.25GHz by changing signal processing software.

Currently, a number of wireless access systems have been available to users. Especially, several new systems can be used on not only 800-6000MHz band that is suitable for cellular communications and broadband wireless access systems but also the lower frequency band such as VHF and UHF bands. This means that most frequency bands adequate for mobile communication systems are fully occupied after...

متن کاملHYRA: A Software-defined Radio Architecture for Wireless Embedded Systems
Traditional Software-defined Radio (SDR) architectures cannot go with the requirements of embedded systems, specially in terms of performance and power consumption. Lowpower FPGAs now reaching the market might soon become a viable alternative to overcome such limitations. The Hybrid Radio Architecture (HYRA) introduced in this paper contributes to this scenario as it explores the Hybrid HW/SW C...
