Abstract
The combination of multiple-input multiple-output (MIMO) system with OFDM techniques is regarded as a promising solution for enhancing the data rates of next-generation wireless communication systems.
SDM is implemented to transmitted different signals simultaneously at the same carrier frequency and to detect the transmitted signals using many techniques such as zero frequency, minimum mean square error with and without decision feedback and maximum likelihood decoding.
Furthermore, orthogonal frequency division multiplexing technique included in the simulation process using the parameters of the IEEE 802.11a standard. The fading channel is modeled by exponentially – decayed Rayleigh fading channel which is based on the indoor WLAN, Least Square (LS) method is used to estimate the channel for each subcarrier.
