Or Ordentlich is an information theorist and Postdoctoral Fellow at MIT hosted by Professor Yury Polyanskiy. Prior to this he was a PhD student at Tel-Aviv University. His thesis “Structured Codes for Wireless Communication” was written under the supervision of Prof. Uri Erez. His main research interests are in the fields of Information Theory, Communication Theory and Signal Processing. In particular, he is interested in the problem of communication in the presence of interference, which is related to all three fields.

The last decade has seen the emergence of wireless communication as a leading technology. While having many clear advantages from the perspective of the end-user, this form of communication introduces numerous new challenges for the communication engineer. A key issue which arises in the context of wireless communication is the presence of interference from other wireless users. In contrast to the wireline scenario, where the channel between a transmitter and a receiver is isolated from its surroundings and is therefore essentially free of interferences, in wireless communication the channel is the open air. Since this “channel” is shared by all wireless users, interference between adjacent users is unavoidable.

Although the problem of communication in the presence of interference is highly important from a practical, as well as theoretical, point of view, not much is known about its fundamental limits. Or’s research is aimed towards making progress in this direction and developing new protocols for communicating over interference-limited networks.
