Abstract
The transmission performance of wireless systems depends on the radio propagation as well as the modulation scheme and signal-to-noise ratio. Therefore, it is essential to evaluate the transmission performance under the radio propagation specified by the target wireless system. Considering the performance evaluation, the theoretical approach is expected to be more attractive than computer simulation because the theoretical approach gives an overview of the transmission performance thanks to being formulated using essential system parameters. We explain the theoretical derivation method of the transmission performance using a simple radio propagation model and then introduce some examples of the theoretical derivation for MIMO and OFDM, which have been widely adopted for recent wireless systems.
