Abstract
Fifth Generation of cellular networks is coming in the next few years and we think that it will not be predicted as a development version of the existing one. The wireless research community aspires to visualize full duplex operation by supporting concurrent transmission and reception in a single time/frequency channel for the sake of improving the attainable spectral efficiency by a Factor of two as compared to the family of conventional half duplex wireless systems. The main challenge encountered in implementing full duplex wireless devices is that of finding techniques for mitigating the performance degradation caused by self-interference. Self-interference suppression will represent one of the main merits that offered by the Fifth Generation Networks. While in the existing version of mobile networks the available spectrum is not sufficiently used, the predicted version will use that spectrum in more efficient manner in such a way that it will be approximately full all the operating time. The object of this paper is to scan the existing techniques that are concerned with Self Interference cancellation on the level of antenna and system design to allow us to suggest some solutions for that problem in the future.
Highlights
Global system of mobile communication has many developments starting from 1980 (1G) passes by many modifications till 2010 that resulted in 4G
It is well-known that the data can be transmitted and received on two separate channels; one channel is uplink and the other is down link to achieve the performance requirements (Key performance indicator), which means that the system must operate at half duplex mode where it can’t TX and Rx on the same frequency band
We present the most important characteristics of the fifth generation of mobile communication technology such as vision, offered services and different types of connectivity
Summary
Global system of mobile communication has many developments starting from 1980 (1G) passes by many modifications till 2010 that resulted in 4G. Fifth generation till has no unique definition [1] and it is expected to be in use in 2020 It is well-known that the data can be transmitted and received on two separate channels; one channel is uplink and the other is down link to achieve the performance requirements (Key performance indicator), which means that the system must operate at half duplex mode where it can’t TX and Rx on the same frequency band. To achieve the vision of the new generation, the requirements must be matched with the market demands
