A Review on Methods of FBMC and other Techniques of Massive MIMO

In this paper we discuss the various methods of implementation of Massive MIMO using filter banks, OFDM, UFMC. The demand for greater output relative to input will see a definite increase in context of wireless system in the coming time. 5G is the most anticipated technology that will surely suffice in dealing with demands in terms of rate of data, latency, increasing number of users online at the same time, improving the quality of service provided etc. The large scale antenna system - popularly known as Massive MIMO (multi input multi output) is the leading technology to realize 5G network. However implementation of this system of antennas is a real challenge that is being faced and with so many ways available for implementation, which one to choose is a dilemma. A recent idea that is gaining momentum is the use of filter bank multicarrier (FBMC). Filter bank architecture is the basis of FBMC. There are various properties of FBMC that encourages its use such as no presence of cyclic prefix, carrier assemblage and ability of self equalization. These parameters are very helpful in achieving many goals such as (i) reducing the complex nature of the system, (ii) reducing the ratio of peak and average power, (iii) reducing delay in the system (also known as latency), (iv) responsiveness to carrier frequency offset and (v) increasing efficiency in the bandwidth provided.
