Abstract :
In this paper, we present some evaluation methodologies for 3G long term evolution (LTE) employing orthogonal frequency division multiplexing (OFDM) from the view of system level. A system simulation platform is established to evaluate the system performance of LTE. Many important research topics, such as packet scheduling algorithms and fractional frequency reuse (FFR) scheme, can be studied through this platform. Some popular scheduling algorithms are evaluated in OFDMA systems for the mixed services, such as real-time (RT) and non-real-time (NRT) services. FFR scheme is proposed in this paper to avoid the co-channel interference. Finally, the system performance of LTE is evaluated under various scheduling algorithms for mixed services with the use of FFR.
