The compatibility discrete fourier transformation (DFT) for MIMO-OFDM system / Muhammad Arif Zulkfli
Multiple input multiple output (MIMO) is a system that has more than one antennas receiver or transmitter at transmitter and receiver station. To improve information or data transfer and also communication performance, orthogonal frequency division multiplexing (OFDM) is purposed. Orthogonal frequen...

Orthogonal frequency division multiplexing (OFDM) is a multicarrier system and available bandwidth is separated into many narrow bands and data is transmitted in parallel on these bands. OFDM also provides robustness, high spectral efficiency to inter symbol interference (ISI). MIMO-OFDM system can provide high transmission data rate, spectral efficiency and reliability for wireless communication system.. But all this system has a problem which is noise.
