The potential capacity gains of coordinated processing in the reverse link of a cellular system are evaluated. Three different matched filter-based receiver schemes, successive intra-cell interference cancellation, successive intra- and inter-cell interference cancellation, and centralized successive interference cancellation, are analyzed considering different path loss exponents and various limiting factors such as non-detectable paths and imperfect interference cancellation. Performance of the three schemes is compared to that achievable by the single user matched filter receiver and by the optimum joint decoding scheme. Capacity gains ranging from 41% up to 183% over the classical single user matched filter receiver are highlighted.

Abstract
The potential capacity gains of coordinated processing in the reverse link of a cellular system are evaluated. Three different matched filter-based receiver schemes, successive intra-cell interference cancellation, successive intra- and inter-cell interference cancellation, and centralized successive interference cancellation, are analyzed considering different path loss exponents and various limiting factors such as non-detectable paths and imperfect interference cancellation. Performance of the three schemes is compared to that achievable by the single user matched filter receiver and by the optimum joint decoding scheme. Capacity gains ranging from 41% up to 183% over the classical single user matched filter receiver are highlighted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
