A Review on DMSTA Based Channel Estimation Techniques for Wideband Affected Massive MIMO Systems

Massive multiple input and output MIMO system is currently considered a promising technology to achieve the 5G generation of mobile communication requirements. There is a large no. of antennas used in transmitter and receiver side. The transmitted wideband signal will be sensitive to the propagation delay of electromagnetic wave across the large array aperture, which is called spatial wideband effect. The purpose of this report is to provide a survey of research related to Spatial wide band effect in massive MIMO System and propose suitable channel estimation techniques for mitigation of spatial wide band effect and pilot contamination problem.
