This thesis is on the IEEE 802.11n standard, also known as Wi-Fi 4, which is the first Wi-Fi standard to introduce multiple-input multiple-output systems. It is based on orthogonal frequency division multiplexing (OFDM) and supports space-time block coding (STBC). To meet the need for selecting in real-time the appropriate modulation and coding scheme from the available set of schemes that the standard offers, we examine the use of the exponential effective signal-to-noise-ratio (SNR) mapping method, known as the EESM method. The EESM method provides a function that maps the SNRs of the OFDM subcarriers into one single SNR value, which has the same system performance when evaluated at the single-carrier additive-white-Gaussian-noise channel. Specifically, in the thesis we develop the EESM method for a system with two transmit antennas and one receive antenna, employing STBC at the transmitter, and utilizing the IEEE TGn Model-B channel. We evaluate the performance of the EESM method in this system and show that EESM provides, in real-time and with low complexity, reliable estimates of the error rate of the modulation and coding schemes that are available by the IEEE 802.11n standard.
