In massive MIMO systems, users on a network can be divided into several user groups of similar spatial antenna correlations. ...
In this case, the dimension of effective channel reduced by outer precoder is important as it leverages the inter-group interference, the intra-group interference, and the performance loss from the quantized ...
Then, the inner precoder cancels out the same-group interference (SGI) with the dimension-reduced effective channels produced by the outer precoder; in this case, the BS exploits the quantized versions ...
