Interference Cancellation With Power Efficiency For Full-Duplex Case Analysis

Interference Cancellation with Power Efficiency using LTE system for Full-Duplex Systems Abstract- Full duplex radios has an important problem which is known as nonlinear distortion, since the receiver RF components must be able to tolerate the high-power SI signal is then gradually suppressed in RX chain as well as LTE channel can be used for increasing the channel performance. It also analyzes, quantifies, and compare two alternative RF cancellation strategies where reference signal is taken either from TX power amplifier (PA) input or output. Analog to digital converter (ADC) is used in addition to linearity analysis. The quantization noise of the ADCs is another significant problem and the increase in maximum transmits power can also cause the nonlinear distortion. In this project, it is shown that, with digitally intensive self-interference cancellation by using LTE (Long Term Evalution) system as our proposed system. This proposed LTE system transmitter data frame is going to receive with less interference cancellation and less power consumption.

I. INTRODUCTION
Full-Duplex (FD) is a radio technology, at which the devices
It results from the fact that the transmitted signal is superposed with the received signal of interest, and as they share the same frequency band, it usually cannot be filtered out. Thus, one of the central problems in studying full-duplex radios is to determine ways to cancel the SI signal down to a sufficiently low level. However, due to several inherent non-idealities in the implementation of SI cancellation stages, e.g., phase mismatch in the cancellation signals and the non-linearity of the amplifiers, there will always be some residual SI after
