METHOD AND DEVICE FOR PERFORMING PRE-COMBINING PROCESSING ON UPLINK MASSIVE MIMO SIGNALS

摘要

Provided are a method and device for performing pre-combining processing on uplink massive MIMO signals in a base station. The method comprises the following steps: breaking down a covariance array signal of an uplink channel estimation from a UE into a plurality of sub-array signals; respectively solving an eigenvalue and an eigenvector of a long-term channel estimation covariance matrix corresponding to each sub-array signal via a recursive algorithm, until the algorithm recursive to a basic pre-combining device can be solved. The present invention has the following advantages compared to the prior art: large-scale array signal processing is performed by breaking down and grouping an array signal corresponding to an uplink signal and respectively performing long-term smooth pre-combining processing on each array group, thereby reducing the computational complexity of a multi-antenna uplink massive MIMO receiver, and increasing signal processing efficiency.
