In this paper, we propose an efficient scheme for side peak cancelation in binary offset carrier (m,n) (BOC(m,n)) with integer modulation order. The proposed scheme reduces significantly the width of the main peak of the auto-correlation function (ACF) and thus the range of influence of the multipath (MP) in BOC-modulated signals. It is based on the use of(More)
The Multiplexed Binary Offset Carrier (MBOC) signal has been recommended as optimized modulation on L1/El frequency band by both United States and European Union communities. MBOC signal is defined on the basis of its spectrum, while different time waveforms can be selected as possible modulation candidates. In this paper we present the different options of(More)
In this paper, an efficient scheme for Multipath mitigation in Global Navigation Satellite System (GNSS), such as Global Positioning System (GPS) and future Galileo, is proposed. It is based on Centered-Finite-Derivatives by using Five-Point-Stencil. By using the aforementioned scheme, the multipath induced bias can be efficiently reduced. In addition,(More)
This paper investigates the application of artificial neural network structures to the problem of nonlinear channel equalization. The difficulties caused by channel distortions such us inter symbol interference (ISI) and nonlinearities can be overcome by equalizers employing neural networks. We present a structure of a nonlinear equalizer with decision(More)
