ABSTRACT
New and difficult services like autonomous cars, smart cities, IoT, 3GPP, etc. are being made possible by the revolution in wireless technology. The channel estimation techniques that correlate to new services that can and will improve performance by applying fewer operations and having a low system complexity are the main topic of this study. The estimating methods for these new services differ depending on the environment in which they operate, the requirement to increase performance in the TD & in the FD's, then, there is a need to reduce system complexity, or the system design's simplicity. Finally, the selection of an appropriate estimating method must be done based on the requirement of realistic applications.
