JOCO
(JOint
source-channel COding-driven digital
baseband design for 4G multimedia streaming)
The
4th generation of wireless systems (4G) will be a globally integrated
communication network interconnecting in a transparent way,
a multitude of heterogeneous networks and systems. A key challenge
for the deployment of 4G will be the definition of a flexible
reconfigurable network architecture that enables simultaneous
optimisation of bandwidth and Quality of Service (QoS) management.
Generally speaking, optimal allocation of user and system resources
may be effectively achieved with the co-operative optimisation
of communication system components. This approach, known as
joint source channel coding and decoding
(JSCC/D), allows for strategies where the source
coding, channel coding, modulation, and possibly network parameters
are jointly determined to yield the best end-to-end system performance.
As a summary the main objectives of JOCO
are:
