    Galileo Receivers - Challenges and Performance

    Get PDF
    This paper addresses the Test User Receivers (TUR) of the Galileo Satellite Navigation System. The paper explains the concept of TURs highlighting the difference between TUR and a commercial receiver. An outline of the high-level requirements for the TUR is provided. Functional and performance requirements are presented. The interfaces between the TUR and the Galileo System are summarized, in particular the signals in space of the Galileo System. The key differences between Galileo and GPS receivers are identified, explained, and discussed

    Highly Efficient Wideband Digital Frequency Demultiplexer

    This paper presents an advanced ASIC architecture for a wideband digital frequency demultiplexer designed for on board satellite communication systems. The structure is able to handle up to 32 uniformly spaced channels extracted from a digital, real frequency division multiplexed signal sampled at 672 MHz; contiguous demultiplexing and remultiplexing is supported. An efficient demux two-stage parallel architecture was developed where all internal coefficients (including the FFT ones) are coded with canonic signed digit technique allowing area saving with respect to 2's complement code. Performance evaluations, in terms of bit error rate, noise to power ratio and gate complexity, were carried out for the architecture definition. Subsequently the design was coded in VHDL and synthesised on a 0.18 μm CMOS technology by means of Synopsys™ tools
