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) have 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 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. This article discusses an evaluation methodology of system-level simulation for a MIMO-OFDMA system. The approach by which the capacity evaluation of the MIMO-OFDMA system was conducted and resulting sum-rate capacity is discussed.
