A maximum-likelihood (ML) coarse symbol synchronization algorithm for OFDM systems in multipath channels is derived. Several simplifying assumptions r...

Connectivity and capacity analysis of ad hoc networks has usually focused on asymptotic results in the number of nodes in the network. In this letter...

A session tree based mechanism provides an efficient method to avoid well-known feedback implosion. However, it is not easy to configure an efficient...

This letter looks at the problem of achieving specific quality of service (QoS) goals of individual flows by flexibly managing resources available to...

We demonstrate that no combined input- and output-queued switch with limited speedup (i.e., smaller than the number of ports) and limited output buffe...
