Two-way training: optimal power allocation for pilot and data transmission
Abstract--In this letter, we consider multiple-input singleoutput (MISO) systems with two-way training based transmission. We focus on the long-term system performance and study th...

Optimal Relay-Subset Selection and Time-Allocation in Decode-and-Forward Cooperative Networks
—We present the optimal relay-subset selection and transmission-time for a decode-and-forward, half-duplex cooperative network of arbitrary size. The resource allocation is obtai...

Optimal parameter estimation for model-based quantization
We address optimal model estimation for model-based vector quantization for both the constrained resolution (CR) and constrained entropy (CE) cases. To this purpose we derive unde...
