Diversity-multiplexing gain tradeoff with peak to average power ratio constraints
Zheng and Tse have shown that over a quasi-static channel, there exists a fundamental tradeoff, known as the diversity-multiplexing gain (D-MG) tradeoff. In a realistic system, to ...

Outer bound and noisy-interference sum-rate capacity for symmetric Gaussian interference channels
A new outer bound on the capacity region of Gaussian interference channels is developed. The bound combines and improves existing genie-aided methods and is shown to give the sum-r...
