In this paper, different error protection strategies in different protocol layers are discussed, in order to reliably broadcast multimedia data within existing wireless networks. In particular, we investigate the performance of additional forward error correction (FEC) in the physical layer, the radio link control (RLC) layer, and the RTP layer for multimedia broadcast and multicast services over...
We consider the transmission over an unknown frequency-selective channel of two independent sources with different application-layer characteristics: one source (such as voice) has a low information rate with a strict delay constraint; the other (such as data) has a high rate but without any delay constraints. We propose a system structure that jointly considers the different decoding requirements...
