Abstract
In this paper, we propose a relative channel estimation error (RCEE) metric, and derive closed-form expressions for its expectation \rm {Exp}_{rcee}and the achievable uplink rate holding for any number of base station antennas M with the least squares (LS) and minimum mean squared error (MMSE) estimation methods. It is found that RCEE and \rm {Exp}_{rcee}converge to the same constant value when M\rightarrow\infty resulting in the...
