Sum Rate of Linear Cellular Systems With Clustered Joint Processing
With increasing demand of spectrally efficient communication systems the search for the rate limits of uplink cellular systems gained momentum. First concrete findings in this regard assumed that all Base Station (BS) receivers cooperate in the uplink channel to jointly process the signals at a centralised receiver - termed as a hyper receiver via unlimited rate links. In this paper, the authors derive the sum rate of the uplink of a linear network of cells when clustered coordinated processing is adopted among the base stations in a generalised fading environment. Various cluster isolation schemes along with an interference allowance scheme are analyzed and compared in terms of achievable sum rate with each other and to the optimum case of a system with central processor.
