With emerge of increasing research in the domain of future wireless communications, massive MIMO (multiple inputs multiple outputs) attracted most of researchers interests. Massive MIMO is high-speed wireless communication standards. A channel estimation technology plays the essential role in the MIMO systems. Efficient channel estimation leads to spectral efficient wireless communications. The critics of Inter-Symbol Interference (ISI) are the challenging tasks while designing the channel estimation methods. To mitigate the challenges of ISI, we proposed the novel blind channel estimation method which based on Independent component analysis (ICA) in this paper. Proposed channel estimation it works for both blind interference cancellation and ISI cancellation. The proposed Hybrid ICA (HICA) method depends on pulse shape filtering and ambiguity removal to improve the spectral efficiency and reliability for MIMO communications. The Kurtosis operation is used to measure the complex data at first to estimate the common signals. Then we exploited the advantages of 3rd and 4th order Higher Order Statistics (HOS) to priorities the common signals during the channel estimation. In this paper, we present the detailed design and evaluation of HICA blind channel estimation method. We showed the simulation results of HICA against the state-of-art techniques for channel estimation using BER, MSE, and PAPR.

“…In wireless systems OFDM is very popular and useful technique because it meets the requirements of future technologies.OFDM stands for Orthogonal Frequency Division Multiplexing. It is a multicarrier modulation scheme used in 4g technologies [7]. It does not have very complex equalizations and it also removes ISI [8].…”

This paper gives the comparison of the Bit error rates of modulation techniques like QAM and PSK for their different order of modulations (M) and for different values of subcarriers (N) by using LS channelestimator. Comparison of bit error rates of various modulation schemes is done to find out the best suited modulation technique for transmitting N no. of subcarriers. LS estimator is a technique used for channel estimation in MIMO-OFDM system. Channel estimation is done at the receiver for compensating the effect of distortions which are created by the channel. LS channel estimator comes under the block type channel estimation technique.
