  This work studies multiple-antenna wireless communication systems based on
super-resolution arrays (SRAs). We consider the uplink of a multiple-antenna
system in which users communicate with a multiple-antenna base station equipped
with SRAs. In particular, we develop linear minimum mean-square error (MMSE)
receive filters along with linear and successive interference cancellation
receivers for processing signals with the difference co-array originating from
the SRAs. We then derive analytical expressions to assess the achievable
sum-rates associated with the proposed multiple-antenna systems with SRAs.
Simulations show that the proposed multiple-antenna systems with SRAs
outperform existing systems with standard arrays that have a larger number of
antenna elements.
