Abstract
Extensive use of Internet and huge demand for
multi-media services via portable devices require the development
of packet-based radio access systems with high transmission
efficiency. Various advanced transmission technologies have
recently been proposed to achieve this challenging goal. However,
few researches have been reported on the design of an integrated
system that can efficiently accommodate these transmission
technologies. This paper considers the design of a packet-based
cellular system for the next-generation radio access. We propose a
novel system framework that can incorporate various
transmission technologies such as link adaptation, opportunistic
packet scheduling, channel coding and multi-antenna techniques.
By analyzing the interoperability between these transmission
technologies, we design a differentiated segments-based OFDM
system, called DiffSeg, that can support heterogeneous operating
conditions in a seamless manner. Simulation results show that the
proposed DiffSeg system can provide near optimum performance
in a wide variation of wireless channel condition.
