Coding and Signal Design Techniques for Reducing Signal Peaks and Interference

Wireless communications is a feverishly active area of research because of the recent explosion in the global demand. Orthogonal frequency division multiplexing (OFDM) is a robust transmission technique that is being considered for the emerging wireless communication systems. Unfortunately, two drawbacks of OFDM are the high peak-to-average power ratio and intercarrier interference caused by frequency errors. Techniques to reduce both, can have significant practical applications. We will develop coding and other techniques for this purpose. The project will produce significant conceptual advances on new coding techniques, efficient signal design methods, and theoretical results of wider applicability.
