One of the most important features in the 4G mobile networks is the
domination of high-speed packet transmissions or burst traffic in the
channels. The same codes used in the 2G-3G networks will be applied to
future 4G mobile or wireless networks, the detection of very short
bursts will be a serious problem due to their very poor partial
correlation properties. Recent study has indicated that traditional
multi-layer network architecture based on the OSI model may not be well
suited for 4G mobile network, where transactions of short packets will
be the major part of the traffic in the channels. As the packets from
different mobiles carry completely different channel characteristics,
the receiver should execute all necessary algorithms, such as channel
estimation, interactions with all upper layers and so on, within a very
short time to make the detections of each packet flawless and even to
reduce the clutter of traffic.
