Abstract-Radio intelligence is a novel approach in wireless communication systems it arises to solve the current saturation of the spectrum. There are three access schemes for intelligence radius: interweave, underlay and overlay. The overlay scheme may allow higher transmission speeds and bandwidth through the application of mitigation techniques or management interference. Through these techniques the quality and efficiency of transmission is guaranteed. This paper presents a study and analysis of these techniques that may be implemented in future wireless communication systems. The characteristics of some of the most common techniques to mitigate interference in the overlay schemes for radio intelligence systems are analyzed.The simulation results are presented in terms of bit error for overlay systems using pre-coding techniques and spatial filtering show the good performance of these techniques in wireless communication systems.Keywords-dynamic spectrum access, interference, overlay, radio intelligence.

Moreover, an administrator is frequently exposed to dangerous conditions as a result of being surrounded by densely distributed moving machines. To address this issue, we propose in this paper to employ a location-based frequency interference management using fingerprinting scheme in industrial environments and its advanced localization schemes based on -NN (Nearest Neighbor) algorithms.Simulation results indicate that the proposed schemes reduce distance error, frequency interference, and any potential danger may be responded immediately by continuous tracing of the locations.

Abstract. In view of the problem of CO frequency interference in the heterogeneous networks of cognitive radio, this paper presents a method of CO processing by macro cellular and micro cellular cells. A beam forming algorithm for maximizing the network of the user is presented, which is based on the orthogonality of multiple antennas and different geographical locations.The simulation results show that the proposed algorithm can effectively improve the transmission speed between the sub users, so as to improve the utilization of frequency.
