Abstract

The ever-growing demand in the market for the high data rate and high spectral efficiency increases the need to use the available band ofspectrum more efficiently. The future is dependent on using the frequency bands more efficiently. The most recent and trending 5G technologyuses the mm Wave band for its transmission. This band in the 60 GHz frequency uses MIMO systems along with many other leadingtechnologies or methodologies like hybrid beam forming, OFDM etc. This paper is mainly focused on one of those technologies which is calledHybrid Beam forming and its optimization using the Kalman’s test. This paper's primary significance is i) the proposal of an integrated beamgenerating implementation that utilises MIMO. ii)To analyze its performance and to optimize it using Kalman’s test. iii) To observe theperformance upon changing various system parameters and analyze the results. Analog only beam forming will be having low spectralefficiency and high-power consumption whereas if we consider fully digital beam forming, we will be having computational complexities.Hybrid Beam forming is a promising technique to overcome the above-mentioned complexities and it is also very reliable in multiuserscenarios.
