摘要: Cognitive radios have been advanced as a technology for the opportunistic use of under-utilized spectrum. radio is able to sense spectrum and detect presence primary users. However, users are skeptical about robustness this sensing process raised concerns with regards interference from cognitive radios. Furthermore, while number techniques aid process, none these verified in practical system. To alleviate concerns, real time testbed required, which can comparison enable measurement evaluation key performance metrics. In paper, we present such testbed, based on BEE2, multi-FPGA emulation engine. The BEE2 connect 18 front-ends, be configured or secondary Inherent parallelism FPGAs allows simultaneous operation multiple radios, communicate exchange information via high speed low latency links
