Wireless Communication is a system for communicating information from one point to other, without utilizing any connections like wire, cable, or other physical medium. Cognitive Radio (CR) based systems and networks are a revolutionary new perception in wireless communications. Spectrum sensing is a vital task of CR to avert destructive intrusion with licensed primary or main users and discover the accessible spectrum for the efficient utilization of the spectrum. Centralized Cooperative Spectrum Sensing (CSS) is a kind of spectrum sensing. Most of the test metrics designed till now for sensing the spectrum is produced by using the Sample Covariance Matrix (SCM) of the received signal. Some of the methods that use the SCM for the process of detection are Pietra-Ricci Index Detector (PRIDe), Hadamard Ratio (HR) detector, Gini Index Detector (GID), etc. This paper presents the simulation and comparative performance analysis of PRIDe with various other detectors like GID, HR, Arithmetic to Geometric Mean (AGM), Volume-based Detector number 1 (VD1), Maximumto-Minimum Eigenvalue Detection (MMED), and Generalized Likelihood Ratio Test (GLRT) using the MATLAB software. The PRIDe provides better performance in the presence of variations in the power of the signal and the noise power with less computational complexity.

Players may stop playing a picked amusement sooner than anticipated for some reasons. A standout amongst the most vital is identified with the way amusement planners and designers adjust diversion challenge levels. Practically speaking, players have distinctive ability levels and may discover common foreordained troublesome levels as too simple or too hard, getting to be noticeably disappointed or exhausted. The outcome might be diminished inspiration to continue playing the diversion, which implies decreased engagement. A way to deal with alleviate this issue is dynamic amusement trouble adjusting, which is a procedure that alters diversion play parameters progressively as indicated by the present player aptitude level. In this paper we propose a constant answer for DGB utilizing Evolutionary Fuzzy Cognitive Maps, for progressively adjusting a diversion trouble, giving a very much adjusted level of test to the player. Transformative Fuzzy Cognitive Maps depend on ideas that speak to setting diversion factors and are connected by fluffy and probabilistic causal connections that can be refreshed progressively. We talk about a few re-enactment tries that utilization our answer in a runner sort amusement to make all the more captivating and dynamic diversion encounters.

“…In the last ten years, this field (i.e.) wireless communications has grown at a fast pace [9]. Almost the electronic circuits has implemented some wireless device, in form of cellular technologies like CDMA, LTE technologies, Bluetooth, Wi-Fi, and to have effective communication in Software-defined radio.…”

The efficient method for detection of unknown wireless devices using software-defined radios (SDR) in wireless communication is proposed to analyze the power loss. SDR analyze the position of unknown parameter and their transmission of power and energy by sensing the carrier frequency and measuring the signal concerning the Received Signal Strengths (RSS) method. RSS based positioning techniques are useful for implementation of low complexity, and they are susceptible to path loss in the programmable field environment. The RSS based techniques evaluate the position of object and transmission of power from unknown devices by assuming the value of path loss failure before estimation. However, the location of the estimation accuracy depends on the discrepancy of the path loss exponent (PLE) of the object. The novelty of the proposed method introduces a novel approach for path loss failure analysis and calculates the power saving of unknown devices in SDR.
