Cognitive Radio
Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access: the policy that addresses the spectrum scarcity problem that is encountered in many countries. Thus, CR is widely regarded as one of the most promising technologies for future wireless communications. To make radios and wireless networks truly cognitive, however, is by no means a simple task, and it requires collaborative effort from various research communities, including communications theory, networking engineering, signal processing, game theory, software-hardware joint design, and reconfigurable antenna and radio-frequency design.
Wireless communication system is the essential part for IoT infrastructure, which acts as the bridge for dual directional communication for data collection and control message delivery. It can be applied to various IoT applications, including mission critical industries, such as power grid, oil field, and cases in our routine life like the smart city. The common challenges and issues on wireless communication for IoT applications: A) Huge volume of sensors with varied types and distributed sites need to be connected, managed and maintained, B) High reliable communication will be required under the environment with lots of interferences, Available spectrum resources will be very limited for new IoT wireless network, C) For harsh outdoor area, low power consumption and simple architecture will be required, In harsh outdoor environment, the installation and maintenance will be more challenging In order to solve those issues, SDR wireless platform can play important role for IoT to support the optimized communication from the senor network to the wide area radio network. The approach is to utilize the IT-based software-defined radio (SDR) technology to complete the entire base band processing on IT platform with multi-cores processors. The acceleration technologies, such as SIMD, vector processing, parallel processing, etc., have been used to speed up the signal processing with extremely low latency. Meanwhile, some wireless optimization technologies are also applied to the whole system, including the dynamic spectrum allocation, interference mitigation, and energy efficiency design.

Cognitive Radio
Cognitive Radio (CR) is an adaptive, intelligent radio and network technology that can automatically detect available channels in a wireless spectrum and change transmission parameters enabling more communications to run concurrently and also improve radio operating behavior.
Cognitive radio uses a number of technologies including Adaptive Radio (where the communications system monitors and modifies its own performance) and Software Defined Radio (SDR) where traditional hardware components including mixers, modulators and amplifies have been replaced with intelligent software.
Unlike conventional radios, which are designed to work with specific waveforms (AM and FM, cellular, digital TV, and Wi-Fi, for example), software defined radios can send and receive many different waveforms, and toggle between them on the fly by means of software code that defines their behavior at any particular moment. Wireless networks have evolved from 1G to 4G networks, allowing smart devices to become important tools in daily life. The 5G network is a revolutionary technology that can change consumers' Internet use habits, as it creates a truly wireless environment. It is faster, with better quality, and is more secure. Most importantly, users can truly use network services anytime, anywhere. With increasing demand, the use of bandwidth and frequency spectrum resources is beyond expectations.
Current radios utilize 4th generation SDR (Software Defined Radio) technologies in which components/modules that have been typically implemented in hardware are replaced by software on an embedded computing device In all previous generations, there was a single dominating technology, i.e., Frequency Division Multiple Access (FDMA) for 1G, Time Division Multiple Access (TDMA) for 2G, Code Division Multiple Access (CDMA) for 3G, and Orthogonal Frequency Division Multiple Access (OFDMA) for 4G.
