Impact of AWGN, Rayleigh and Rician FadingChannels on BER Performance of a Cognitive Radio Network
Ammar Izzeldin Mohammed, Khalid Hamid Bilal Abstract— The paper discusses the model building of the cognitive radio system by using MATLAB Simulink model. This model is a useful tool for BER (Bit error rate) performance evaluation for the real data communication by the cognitive radio system under different communication channels and Multi level Quadrate Amplitude Modulation which are described...
متن کاملS Imulation and a Nalysis of C Ognitive R Adio S Ystem Using Matlab
The increasing demand of wireless applications has put a lot of limitations on the use of available radio spectrum is limited and precious resource. Many survey of spectrum utilization shows that entire spectrum is not used at all the times, so many of the radio spectrum is underutilized. Some of the frequency bands in the spectrum are unoccupied, some of the frequency bands less occupied and f...
متن کاملSpectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants
The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. This paper introduces an i...

Residential and commercial sectors are the main consumers of energy. According to available data, these two sectors account for more than one-third of total energy use. Moreover, heating and cooling systems contribute to the major share of energy use in a building. The current research economically evaluates the radio-frequency heating systems for use in residential buildings. A building in Dis...
متن کاملPeriodogram Spectrum Sensing Using Blackman Tukey Method in Matlab
Wireless communication is the fastest growing industry from many aspects. Increasing number of users imposes bandwidth constraints on the communication system. Cognitive Radio (CR) finds the solution to this problem and uses the free portion of the spectrum. Energy based spectrum sensing is the simplest way and in frequency domain it can be performed by using Periodogram based spectrum sensing....
