On the Asymptotic Sum Rate of Downlink Cellular Systems With Random User Locations

We consider a downlink cellular communication system with a multi-antenna base station (BS). A regularized zero forcing precoder is employed at the BS to manage the inter-user interference within the cell. Using methods from random matrix theory, we derive a deterministic approximation for the achie...
