PHOENIX goals

Main objective The aim of PHOENIX project was to develop a scheme offering the possibility to let the application world (source coding, ciphering) and the transmission world (channel coding, modulation) to talk to each other over an IPv6 protocol stack (network world), so that they can jointly develop an end-to-end optimised wireless communication link. The design trade-offs of interactive wireless video systems were studied and performance comparisons will be provided both in the context of existing and future generations of wireless systems.

To reach this goal, the three following main axes were followed:

• develop innovative schemes to enable end-to-end joint optimisation over wireless links. This includes the development of flexible channel coding and modulation schemes, the adaptation of existing source coding schemes with respect to their ability for JSCC/D and the development of new ones specifically optimised for this purpose
• establish efficient and adaptive optimisation strategies that will jointly control the coding blocks and realistically take into account the system limitations and specifications, such as the presence of ciphering, the presence of one or several wireless hops
• build a global network architecture based on joint optimisation for future wireless systems. This objective includes the development of the transparent network communication approach which will allow to apply the optimisation strategies in any kind of fully IP-based network.
