Recently, the Long-Term Evolution (LTE) system has emerged as a major concern within the 3rd Generation Partnership Project (3GPP and 3GPP2). Orthogonal Frequency Division Multiple Accesses (OFDMA) has been considered within the LTE system as a major technology for cellular radio access. In addition, numerous research groups have proposed the incorporation of technologies such as multi-user scheduling, Multi-Input and Multi-Output (MIMO), and Adaptive Modulation and Coding (AMC) into OFDMA. However, system-level simulation is required to assess how these technologies interact and to evaluate and optimize each technology with respect to system-level performance in real cellular environments.
