Walsh Spectral AnalysisSiemens, Karl-Hans 06 1900 (has links)
<p> Walsh functions are defined both by recursive and non-r~cursive
equations. A synopsis is given of the properties of Walsh functions
relevant to this thesis. Two algorithms for simple evaluation of an
arbitrary point on a Walsh function that use only the binary codes for
the parameters of the Walsh function result from the non-r~cursive
definitions. Direct hardware implementation of the evaluation algorithms
yields programmable digital Halsh function generators. One of the
generators, which produces functions that are free of hazards or ambigious
states, is modified to produce a parallel array of Walsh functions.
This generator is used in a Walsh Spectral Analyzer that evaluates
simultaneously several Walsh series coefficients of an input signal. </p> <p> Walsh series analysis and the concepts of the design of a digital
Walsh Spectral Analyzer are discussed. The equation that is used to
determine a Walsh series coefficient is modified so that each portion of
the equation can be manipulated conveniently by a digital instrument.
Although the instrument was designed primarily to analyze periodic waves,
extensions to the design can be made to accommodate aperiodic signals.
Signals with frequencies from the audio range downwards can be analyzed
by the Walsh Spectral Analyzer. </p> <p> Walsh series to Fourier series conversion is dealt with. It has been found that the Fourier coefficients of signals that are limited either in frequency or in sequency can be evaluated precisely using a
finite number of Walsh coefficients of the same signal. A dual
relationship holds for Fourier to Walsh series conversion. The Fourier
series coefficients of Walsh functions comprise part of the conversion
relationships. The Fourier transforms of Walsh functions, from which
the above coefficients can be obtained, are derived in non-recursive
form. </p> / Thesis / Doctor of Philosophy (PhD)

Towards a Low Complexity Implementation of a Multi-H CPM DemodulatorGuéguen, Arnaud, Auvray, David 10 1900 (has links)
ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Multi-h Continuous Phase Modulation (CPM) is a promising waveform for aeronautical telemetry because it is a compact spectrally efficient constant amplitude modulation. It has been selected as the Advanced Range Telemetry (ARTM) tier II waveform owing to these qualities. However, it is also a complicated waveform that has the reputation of suffering from complex demodulation processing and high sensitivity to transmission impairments and in particular synchronization aspects. In this paper we review a set of complexity reduction techniques that intend to bring this waveform into the domain of operational telemetry waveform, by allowing low complexity hardware implementation without sacrificing performance or robustness. Most techniques are adjustments of recent literature results, concerning both demodulation and synchronization. Computer simulation of a receiver implementing theses techniques shows negligible performance loss compared to optimal coherent demodulation with perfect synchronization. Hardware implementation confirms that nearly optimal performance can be achieved with hardware resource currently available in middle range FPGAs.

Design And Implementation Of A Hardware Level Content Networking Front End DeviceBuboltz, Jeremy Layne 01 January 2007 (has links)
The bandwidth and speed of network connections are continually increasing. The speed increase in network technology is set to soon outpace the speed increase in CMOS technology. This asymmetrical growth is beginning to causing software applications that once worked with then current levels of network traffic to flounder under the new high data rates. Processes that were once executed in software now have to be executed, partially if not wholly in hardware. One such application that could benefit from hardware implementation is high layer routing. By allowing a network device to peer into higher layers of the OSI model, the device can scan for viruses, provide higher quality-of-service (QoS), and efficiently route packets. This thesis proposes an architecture for a device that will utilize hardware-level string matching to distribute incoming requests for a server farm. The proposed architecture is implemented in VHDL, synthesized, and laid out on an Altera FPGA.

A Blind Partially Coherent Multi-H CPM Receiver for Aeronautical TelemetrySamad, Shaheen 10 1900 (has links)
ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / Multi-H Continuous Phase Modulation is a highly bandwidth efficient constant amplitude modulation scheme. Because of these qualities it was selected as the Advanced Range Telemetry (ARTM) tier II waveform. In the past, two demodulation techniques have widely been proposed, coherent detection and non-coherent detection. This paper presents a receiver design that implements a hybrid, partially coherent detection scheme that takes advantage of the positive aspects of both coherent and non-coherent detection. Because complete phase recovery is not required, the hybrid receiver performs better in environments with fast fading, strong phase noise, and multi path when compared to the traditional coherent receiver. The hybrid receiver can also acquire and reacquire signals much faster than conventional coherent receivers. The hybrid receiver design implements a partial carrier detection scheme that utilizes phase information that performs much better in AWGN environments than typical non-coherent receivers. Simulation results show that the hybrid receiver has low implementation loss compared to the optimal Maximum Likelihood Sequence Estimation (MLSE) receiver.
