Reconfigurable Software Defined Radio and Its Applications

چکیده
Currently, most Software Defined Radio (SDR) related products and researches focus on analog communication and voice transmission. In this paper, we propose a SDR platform with digital data communication capability. This platform consists of Field Programmable Gate Array (FPGA) based radio hardware and open source SDR software modules. The main features include: 1) Radio Spectrum Sensing; 2) Reconfigurable Radio Modules; 3) Link for Digital Data Communication. Based on the proposed SDR platform, we could easily reconfigure its radio modules and discover the spectrum hole to achieve better communication quality. These features are important basis to accomplish Cognitive Radio (CR) technologies.

A reconfigurable microstrip patch antenna with RF pin diode switches is implemented for dual band of 2.4 GHz and 5.6 GHz WLAN Software Defined Radio (SDR) applications. For the dual band SDR system, the use of a single antenna with a wide bandwidth to cover both of the bands can be limiting for low power level signal applications due to wideband noise as well as changing radiation pattern at di...
