A New Upper Bound for a Binary Additive Noisy Multiple Access Channel with Feedback
— We use the idea of dependence balance [1] to obtain the first improvement over the cut-set bound for the discrete memoryless multiple access channel with noiseless feedback (M...

Training Design for CFO Estimation in OFDM Over Correlated Multipath Fading Channels
— Carrier frequency offset (CFO) estimation is a key challenge in multicarrier systems such as OFDM. Often, this task is carried out using a preamble made of a number, say J, of ...

Diversity Multiplexing Tradeoff in Multiple Antenna Multiple Access Channels with Partial CSIT
Abstract— We derive a lower bound on the diversitymultiplexing tradeoff for multiple antenna multiple access channels using temporal power control (PC). We quantify the substanti...
