Abstract: We establish a lower bound on the noncoherent capacity pre-log of atemporally correlated Rayleigh block-fading single-input multiple-output SIMOchannel. Surprisingly, when the covariance matrix of the channel satisfies acertain technical condition related to the cardinality of its smallest set oflinearly dependent rows, this lower bound reveals that the capacity pre-log inthe SIMO case is larger than that in the single-input single-output SISOcase.
