This paper describes an efficient design and implementation of orthogonal frequency division multiplexing-based Cognitive Radio to achieve the reliable transmission and reception of biomedical signals over a wireless channel. This concept can be used in wireless healthcare applications where medical information can be transferred through wireless networks for remote medical procedures or examinations. The main purpose of choosing Cognitive Radio is to efficiently utilize the available spectrum. As Cognitive Radio employs smart wireless devices with awareness, sensing, learning, and adaptation capabilities, it proves to be the best solution to solve the spectrum scarcity problem. Frequency bands that are not being used by the primary (licensed) users are utilized by Cognitive Radio users. The requirements of Cognitive Radios can be fulfilled largely by employing the orthogonal frequency division multiplexing technique. Using this technique, signals can easily be adapted to channel conditions and capacity requirements, which make it suitable for Cognitive Radio applications. The radio frequency spectrum utilization can be enhanced, and interference to other users can be minimized largely using orthogonal frequency division multiplexing-based Cognitive Radio. In this paper, we investigate the opportunistic access of the white space spectrum for healthcare applications. We propose a framework for the remote monitoring and analysis of patient health based on Cognitive Radio.
