Dynamically Reconfigurable FFTs for Cognitive Radio on a Multiprocessor Platform
نویسندگان
چکیده
Multiprocessor platforms have been proposed as an enabling technology for Cognitive Radio. In this paper, we explore various FFT implementations on a multiprocessor prototype platform as building components for OFDM based Cognitive Radio. The results show that our FFT implementations on the multiprocessor platform are fast and energy efficient. Moreover, the FFT implementations can be dynamically reconfigured with relatively small reconfiguration overheads.

Cognitive Radio on a Reconfigurable MPSoC Platform
Due to the explosive growth of wireless communication, the demands for radio spectrum are rapidly increasing. It is very difficult to accommodate new wireless services under the current spectrum allocation scheme. On the other hand, the allocated spectrum is not efficiently utilized. Cognitive Radio is proposed as a technology to solve the imbalance between spectrum scarcity and spectrum under-...
متن کاملTemperature-Power Consumption Relationship and Hot-Spot Migration for FPGA-Based Systems
Heat emission and temperature control in an electronic device are highly correlated with power consumption as well as to equipment’s reliability. Within this context, this chapter discusses a possible solution to restrict the processing component’s heat emission in FPGA-based systems (e.g., Cognitive Radio [CR] equipment). It also describes the implementation, on reconfigurable FPGA based circu...
