Abstract
A method and apparatus for performing distributed computation of precoding estimates within a DAS. An RRH comprises a receiver component arranged to receive uplink signals from active user devices. The RRH further comprises a processing component arranged to perform channel estimation for each active user device m, based on the received uplink signals, to obtain channel estimates Hbetween each active user device m and the RRH, compute intra-RRH interference precoding estimates Ffor each active user device m based on the channel estimates H, and solve interference-free conditions to obtain inter-RRH interference precoding estimates for each RRH j within the DAS.
