Turbo-coded APSK modulations design for satellite broadband communications
This paper investigates the design of power and spectrally efficient coded modulations based on amplitude phase shift keying (APSK) modulation with application to satellite broadband communications. APSK represents an attractive modulation format for digital transmission over nonlinear satellite channels due to its power and spectral efficiency combined with its inherent robustness against nonl...
متن کاملEHF Satellite Communications-on-the-Move Blockage Channel Modeling
In the next-generation Transformational Satellite Communications System, one essential element is to provide satellite communication to on-the-move terminals, which suffer from intermittent channels due to blockages by objects in their environments. Presented is our approach for modeling these blockage channels for different environments, in order to allow accurate prediction of system behavior...
متن کاملOverview of PHY-Layer Design Challenges and Viable Solutions in W-Band Broadband Satellite Communications
The exploitation of Extremely High Frequency (EHF) bands for broadband satellite communications really represents a challenging frontier for aerospace R&D. In few time, ALPHASAT mission (through the Technology Demonstration Payload 5) should test Q/V band (40-50GHz) digital satellite transmission. Moreover, a lot of effort is spent to study the feasibility of broadband links in W-band (70-110GH...
متن کاملFractal Interpolation Functions as PN Waveform Generators for Broadband Communications
This paper is concerned with the novel use of Iterated Function Systems (IFS) as generators of Pseudo-Noise (PN) spreading waveforms for broadband communications applications. Motivation for this proposal indirectly arises from the recent interest in alternative methods of spread spectrum modulation, for example, via the use of syn-chronising chaotic carriers and localized wavelet lters. IFS re...
متن کاملThe European Satellite Telecommunications Regulatory Framework for Broadband Communications
By its nature, the satellite sector is the most “pan-European” of all communications infrastructures and services. Unlike any terrestrial network, satellite networks can provide coverage to all parts of Europe. This strength of satellite networks, nonetheless, creates a great regulatory challenge. Due to wide satellite coverage, operators depend on harmonized spectrum allocations. The services ...
