Limits of synchronization on communication
The design of waveforms for optimal transmission over wireless channels is an old problem. How the bandwidth and power commodities on an individual link can be used to achieve reliable communication is what defines the core of communication and information theory. What is less acknowledged is the role of synchronization and signal processing in meeting these limits. Synchronization, channel acquisition and decoding complexity are the greatest limitations to achieving efficiency.
Our work has focused on block transmission systems, linear filter-bank precoding, and MIMO models. The block transmission precoding model is the most commonly used framework to design modems today. To close the gap between the mathematical theory of communication and what is practically achievable in the context of bursty packet transmission with the physical limitations of our DSP hardware, it is necessary to find effective ways to process signals in blocks.
