Title
Modern Antenna Design for Wireless Communications: Challenges and Perspectives
Speaker
Steve H. Wong, Acting Assistant Professor, Stanford University
Abstract
It is now at a fascinating time in the history of the wireless communications. Numerous wireless communications systems have been successfully developed in recent years. Wireless devices such as cell phones, tablets, laptops, Bluetooth earphones, game pad controllers, GPS receivers and security sensors are very common in our daily life. They require different kinds of antennas with different characteristics for enhancing their performance in connectivity, stability and data rate. Modern antenna designs are required to be small in size and wide in bandwidth, which are contradicting requirements, as governed by the well-known Chu’s limit. This seminar provides participants with comprehensive coverage of a wide variety of small antenna designs related to mobile communications, satellite communications, and millimeter wave applications. The development of small antennas for modern wireless communications with different generic antenna technologies will be given. Major milestones, design challenges and perspectives will be discussed.

Title
Recent Advances on Error Correction Coding with non-binary LDPC Codes
Speaker
Prof. David Declercq, ENSEA in Cergy-Pontoise
Abstract
In this tutorial, the iterative decoding techniques for non-binary LDPC codes will be presented, both from the theoretical aspects of Belief Propagation and its analysis, and from more practical aspects of efficient implementation. In a first part, introduction on error correction coding with LDPC will be presented, and the main differences between iterative BP decoding of binary and non-binary LDPC codes will be highlighted. Then, in a second part, the recent solutions proposed in the literature to reduce the complexity of non-binary decoders, both for memory storage and computational burden reduction, will be presented. Finally, in a third part, some applications where non-binary LDPC codes show their best potential will be discussed.
Biography
David Declercq was born in June 1971. He graduated his PhD in Statistical Signal Processing 1998, from the University of Cergy-Pontoise, France. He is currently full professor at the ENSEA in Cergy-Pontoise, and CTO of Codelucida©, LLC. He is the general secretary of the National GRETSI association, and Senior member of the IEEE. He is currently the recipient of junior position at the “Institut Universitaire de France”.
His research topics lie in digital communications and error-correction coding theory. He worked several years on the particular family of LDPC codes, both from the code and decoder design aspects.
Since 2003, he developed a strong expertise on non-binary LDPC codes and decoders in high order Galois fields GF(q), with q>>2. A large part of his research projects are related to non binary LDPC codes. He mainly investigated two directions: (i) the design of GF(q) LDPC codes for short and moderate lengths, and (ii) the simplification of the iterative decoders for GF(q) LDPC codes with complexity/performance tradeoff constraints.
David Declercq published more than 30 papers in major journals (IEEE-Trans. Commun., IEEE-Trans. Inf. Theo., Commun. Letters, EURASIP JWCN), and more than 90 papers in major conferences in Information and Communication Theory.
