channel coding

Current work in channel coding studies both the capacities and the strategies by which those capacities can be achieved for a variety of channels relavent to network and wireless communications applications. Examples of channels under consideration include the broadcast channel, over which a single user communicates information to a collection of recipients, and a variety of models for time-varying channels. Both of these families of channels play central roles in a wide variety of wireless and networked communications applications.


One example of ongoing work on the topic of channel coding theory concerns the study of broadcast channel capacities. While the capacity of broadcast channels has been studied in the literature for several decades, the solution to the broadcast capacity problem for general broadcast channels remains unsolved. Ongoing work in channel coding theory proves the capacity of Gaussian broadcast channels with finite intersymbol interference and demonstrates an optimal strategy for achieving that strategy.
