In recent years with the explosive growth of applications over wireless networks, the solicitation for radio spectral has been increased significantly. The issue in spectrum scarcity is not related to the physical shortage of the spectrum, but underutilizing of it. Recently, Federal communication Commission (FCC) proposed the notion of secondary spectrum access by cognitive radio (CR) to improve spectrum utilization. CR is a wireless communication technology which can changes its transmission parameters according to interaction with the environment in which it operates.
The process of transmitting several different signals via a single carrier is known as multiplexing. Orthogonal Frequency-Division Multiplexing (OFDM) is known as the most appropriate technique for multiplexing process. OFDM is the most competent multiplexing technology for cognitive radio because of its unique characteristics such as; the receiving etiquette, spectrum shaping, and flexibility. In this paper, we discuss the various aspects of applying OFDM over CR technology.
