Multimedia Data Transmission over Mobile Internet using Packet-Loss Punctured (PaLoP) Codes

A very flexible transmission system for multimedia over mobile internet is proposed. For a mobile internet scenario a combination of a lossy packet data network and a mobile network is assumed. Conventional solutions are based on a separation of both networks. The new system is able to manage both packet-losses and bit errors in a single decoding step without any transcoding. Furthermore, the system can be adapted easily to the current channel states of both networks in a very flexible way with a minimum of signalization overhead. In a simulation example the performance of the new system is shown for short block-length speech transmission using recursive systematic convolutional codes and for large block-length data transmission using a parallel concatenated convolutional code
