Bidyalaxmi Devi Tensubam, Nongmaithem Lalleima Chanu, Sonika Singh . A Study on Recent Advancements in MIMO-FBMC Systems. International Journal of Computer Applications. 98, 17 ( July 2014), 1-5. DOI=10.5120/17272-7697
Multicarrier (MC) techniques when combined with Multiple Input Multiple Output (MIMO) technology increases the throughput and QOS of the system. OFDM with its unique capability of converting the frequency selective channel into a set of frequency flat channel have proved to be one of the best multicarrier technique that can be applied to MIMO channels. However, OFDM suffers from Bandwidth loss due to the addition of cyclic prefix. Filter bank multicarrier (FBMC) modulation system on the other hand, is highly bandwidth efficient but its application to MIMO channels is still a subject of study to various researchers for the past decade. So far, only FMT based FBMC system offers same flexibility as OFDM in adopting MIMO techniques. This paper presents the various advancements or methods proposed to enhance the flexibility of FBMC systems (FMT,CMT,OFDM-OQAM) while adopting MIMO techniques mainly highlighting the ISI and ICI mitigation methods through improved decoding techniques, equalization schemes and modified FBMC schemes.
