The performance of the interference canceller for frequency reuse satellite communications is degraded due to the nonlinearity contained in the transponder. This paper proposes two types of compensation technique by putting nonlinear functions in both replica generator and receiver input. By conducting computer simulation, it has been proved that the former method is very effective and gives significant...
This paper proposes an effective iterative clipping (IC) on a coded carrier interferometry OFDM (CI/OFDM) system for improving the system performances over the nonlinearity of a solid state power amplifier (SSPA). An additional filtering is not required to remove the out-of-band (OOB) spectrum radiation as required in the conventional clipping method. The IC is designed with a minimized computational...
The carrier super-positioning satellite system is a promising telecommunication system because the frequency efficiency is double that of existing satellite systems. In this technique, we use the same frequency band for inbound and outbound signals that is currently used in separated bands. So, we need to cancel the undesired signal and pick up the desired signal from the received signal to implement...
This paper addresses the design and performance evaluation of an interference canceller for frequency reuse satellite communications in a channel containing a nonlinear device. In this study, a reference simulator has been developed for the evaluation of an interference canceller for P-MP (point to multi-point) satellite networks. In the interference canceller, a precise replica of an unwanted signal...
This paper proposes a new technique for peak-to-average-power ratio (PAPR) reduction without spectrum broadening for Carrier Interferometry orthogonal frequency division multiplexing (CI/OFDM) system. Recently, Carrier Interferometry (CI) code is becoming an interesting code for reducing the PAPR of OFDM system. However, for guaranteeing the low PAPR as the PAPR of single carrier (i.e. by about 4-6dB...
