Abstract
This paper mainly studies data transmission DT rate in the modern communication systems. Increasing the need to improve the sensitivity of the control systems to detect low signals weak capacity density in view of the increasing communications systems new radio that use the capacity is decreasing and the scope of the taking of spaciousness and frequencies are on the rise. This proposed approaches Methodology: Of the combined macro cellular and micro cellular networks on the principles of the cognitive radio, Provide in parallel with the work of the main GSM network to transfer data at a rate of several tens of megabits per second depending on the High-speed for Data transmission in GSM networks based on Cognitive Radio (CR) technology and its various aspects that may play a very important role in the field of next generation wireless communication networks.
Highlights
Wireless communication is the fastest growing sector of the communication industry
The proposed Study spectrum sensing in Cognitive Radios secondary the demand for spectrum in wireless environment has grown substantially due to the widespread use of smart phones
We have proposed a cognitive radio which senses and splits the spectrum
Summary
Wireless communication is the fastest growing sector of the communication industry. In this exact sense, it has captured the attention of everyone in the whole communications market. The data transfer rate in the modern communication systems is increased due to the usage of high-level signal modulations requiring greater signal/noise ratio at the receiver input. In this regard, the claimed characteristics of UMTS and LTE systems in terms of the data transfer rate can be achieved only at a small distance from the BS. In these circumstances, the task of searching and investigating new ways of cellular networks building in order to provide high data rates is of immediate interest at the moment and, first of all, it refers to GSM, the most common standard for cellular communications. Instead of using N-Modulator and demodulators in MCM, which can be generated by IFFT operation, known as OFDM, This is how fast operation is implemented on a DSP chips in a modern communication systems
