Abstract

Currently 5G is research hotspot in communication field, and one of the most promising wireless transmission technologies for 5G is massive multiple input multiple output (MIMO) which provides high data rate and energy efficiency. The main challenge of massive MIMO is the channel estimation due to the complexity and pilot contamination. Some improvement of traditional channel estimation methods to solve the problem in massive MIMO have been introduced in this paper. Besides, the hardware acceleration is useful for massive MIMO channel estimation algorithm. We discuss the relate work about hardware accelerator of matrix inversion and singular value decomposition which are the main complex operations of channel estimation. We find that the memory system, network of processing elements and the precision will be the main research directions for the hardware design of large-scale data size.
