We consider the problem of soft-detection for communication systems employing double differential modulation and forward error correction codes, for e...

Adaptive playout algorithms rely on estimates of network delays to calculate playout times of voice packets. Typically, network estimators are either...

We propose modified random early detection (MRED) gateways for congestion avoidance in TCP/IP networks. MRED aims at providing better control over the...

This letter presents a new admission control policy inspired in the framework of proportional differentiated services (PDS). While most of previous PD...

Orthogonal space-time block codes (OSTBCs) are simple space-time codes that can be used for open-loop transmit diversity systems. OSTBCs, however, can...
