Multiple-input multiple-output (MIMO) systems technology has been used in combination with OFDM (orthogonal frequency division multiplexing) to come up powerful air-interface solutions for use in next-generation digital wireless communication. MIMO/OFDM technology has been adopted by different wireless standards such as Wi-Max, W-LAN (wireless local area networks), and 3G-LTE and 4G-LTE (third and fourth generation Long-Term Evolution) mobile technology. This is because MIMO/OFDM-based channels offer high data transmission rates over multiple paths and frequency selective fading channels (Kakadiya, Solanki, Hadia & Rathod, 2013).
How Adaptive algorithms work with MIMO/OFDM:
Mechanism of work:
Channel estimation in MIMO-OFDM systems is a difficult task due to frequent changes in channel Continue reading...
