Senior Researcher and Adjunct Professor
Gary Lomp joined the NYU Tandon School of Engineering recently after a lengthy career track in private industry. He is an expert in Communication Theory and Optimal Receiver Design, having been awarded 97 US patents in that and related fields to date. He was a pioneer in the evolution of Cellular from analog to digital, and from 2G to 3G (W-CDMA) and beyond (LTE). In the military communications realm, he has worked extensively in the areas of Jam Resistant Voice Communications, Efficient Signal Coding, Low Probability of Intercept (LPI) Signals and Countermeasures and Emitter Location and Ranging. His other research interests include Classical Network Theory, Linear System Theory, Wiener-Hopf Control Theory, Stochastic Processes and Statistical Algorithms.
Embracing rigorous scientific thinking in both the creation (teaching, training, managing) and personal application of engineering discipline, Dr. Lomp has worked for four decades in the advanced Digital Signal Processing (DSP) and Electronic Communications fields, in particular Wireless. Always invested in the newest ideas, and combining advanced research skill with consistently accurate and perceptive market understanding, he has operated at every level of the electronics industry, from basic research to business founder and senior executive. With a technical focus on advanced product development – from requirements and opportunity analysis to mathematical conceptualization and theory to detailed implementation – his philosophy couples rigorous technical excellence with creativity channeled through clear value articulation. Notably, Dr. Lomp provided fundamental transformative leadership as former CTO at InterDigital Communications Corporation and, as General Manager of a new technology business unit he created, laid the foundation for a viable and profitable technology business.
On a personal level, Dr. Lomp believes that the best results come from the best preparation and that true excellence in the art of engineering is based on a philosophy of maximum knowledge, competently applied. His affinity for continuous learning resonates in his manner of interaction with colleagues, clients and students and his enduring friendship with his former teachers at Polytechnic (Brooklyn Poly), whose inspiration lives on after four decades.
In private practice, Dr. Lomp has also served effectively as a technical consultant and as an expert witness in several high-profile Intellectual Property matters and has testified before the U.S. International Trade Commission (ITC) and in Federal Court and at the US Patent and Trademark office on multiple occasions.

Research Projects
One of the areas of research I have worked in is Equalization of Digital Communucation Channels perturbed by multipath. An interesting problem in this area is the equalization problem for offset modulations, such as O-QPSK, which is popular because of its behavior under nonlinear amplifier effects. It has been recognized that, due to the interleaving of the I and Q samples, equalization should be determined so as to minimize only the portion of the intersymbol interference (ISI) of interest (relevant to decision) at the sample time. This means that the imaginary component may be ignored during I-samples and the real component may be ignored during Q-samples. The paper derives in a unique way the optimal equalization filters in both the linear and nonlinear (decision feedback or DFE) cases. The solution provides for the first time a closed form definition of the optimal equalizer filters as well as the minimum mean squared error that is obtained. One reason this problem has eluded general treatment is that one encounters a Wiener-Hopf factorization of a 2 by 2 matrix spectral function. While this is a solved problem, the factors obtained do not relate easily to the underlying scalar channel transfer function. This difficulty is circumvented by a employing clever isomorphism in which the complex-valued signals and system functions are embedded in a 4-dimensional (odd-even, real-imaginary) real vector space. The equalizer in the offset case is shown to be distinct in architecture and performance from the conventional non-offset case. A comprehensive and tutorial unified analysis is presented that allows these cases to be compared directly as a function the multipath channel.
This work has also been extended to the MIMO case and some results in that area are also available. In particular, I have shown that MIMO processing of wideband (large instantaneous bandwidth) communication signals is as efficient as, if not more efficient than, MIMO processing of multicarrier narrowband signal formats such as OFDM. This is important for applications in which the undesirable large peak-to-average power ratio (PAPR) of OFDM is a concern.
Also in connection with the problem of signal transmission, I have developed a generalization of OFDM that is appropriate for channels that exhibit dispersion in both the frequency as well as time domain. Doppler induced by platform motion is an example.
Another problem I have worked on is called Tessellation of the Sphere. This the problem of placing points on the surface of an N-dimensional (real) sphere in a manner that maximizes the minimum Euclidian distance between any two points. It is a problem with a long history. It can be extended to 2N-dimensional space, and in particular, one can consider the problem of tessellation in unitary (N-dimensional complex) space. In this case, the points may be taken as signal vectors in an I-Q (complex baseband) communication system. My interest is in determining such complex constellations that have special properties that render their use in power and bandwidth limited digital communications more efficient.
The above research leads to several interesting mathematical problems. Two of these are:
1. Finding maximal abelian subgroups of a (transitive) permutation group
2. Simultaneous singular value decomposition of a family of matrices and approximations thereof
