The use of information theory to design waveforms for the measurement of ex tended radar targets exhibiting resonance phenomena is investigated. The target impulse response is introduced to model target scattering behavior. Two radar waveform design problems with constraints on waveform energy and durat ion are then solved. In the first, a deterministic(More)
The use of sets of multiple spreading sequences per user in multicarrier code-division multiple-access (CDMA) is investigated. Each user is assumed to have a distinct set of spreading sequences, with a different spreading sequence for each carrier in each user’s set. We show that when these sets of sequences are chosen to be the mutually orthogonal (MO)(More)
Imbalances in the regulation of pro-inflammatory cytokines have been increasingly correlated with a number of severe and prevalent neurodevelopmental disorders, including autism spectrum disorder, schizophrenia and Down syndrome. Although several studies have shown that cytokines have potent effects on neural function, their role in neural development is(More)
As an essential fixture of modern society, electricity is often taken for granted. In many cases, it becomes invisible or is ignored until it is not there or it is time to pay the electric bill. Electricity has been around for well over a century, and the march of industry and progress have created the most complex interconnected system in existence. In a(More)
In this paper, we present an approach to the design of orthogonal, Doppler tolerant waveforms for diversity waveform radar (e.g. MIMO radar). Previous work has given little consideration to the design of radar waveforms that remain orthogonal when they are received. Our research is focused on: (1) developing sets of waveforms that are orthogonal on both(More)
In this paper, we present a novel concatenated trellis coded modulation (CTCM) scheme for limited diversity order fading channels. Examples for such channels include those encountered in indoor wireless networks like IEEE 802.11. It is first shown that when the diversity order afforded by the channel is fixed, bit interleaved coded modulation (BICM) is no(More)
It is often advantageous to acquire pulse-echo gound-penetrating radar (GPR) measurements from antennas that are offset from the air–ground interface by a nonnegligible distance, either because the ground’s surface is rough, or because measurements must be collected remotely. This paper describes the effects of incorrectly estimating the location of the(More)
