Summary: | 碩士 === 國立東華大學 === 電機工程學系 === 101 === SDR (Software Defined Radio, SDR) is a radio communication system defined by software, in which a software architecture specifies the hardware components. These hardware components include filters, amplifiers, modulators, and demodulators. They can be defined through system software and do not require substantial changes to the hardware. They can also be redefined according to needs. The cognitive radio (Cognitive Radio, CR) technology is based on software radio, and this technology is used to solve the problem of low-frequency spectral efficiency. In this thesis, Microsoft SORA (Software Radio) is used to evaluate the performance of Wavelet-Based Denoising Algorithm for Cognitive Radio, and two laptops with SORA system are constructed to build the principles of experimental cognitive radio environment. To achieve the transfer packets and sniffer the transmission by iperf, finally we can analyze the performance of the energy detector by using actual data.
