摘要：
The capacity of zero-outage scheme with imprecise channel state information at the transmitter side (CSIT) for frequency flat, single-input multiple-output (SIMO) channels is examined. It is shown that when CSIT is not precise, the receiver signal-to-noise-ratio fluctuates and the scheme suffers from communication outages. Exact analytical expressions characterizing the outage capacity, the additional power required to compensate the effect of noisy CSIT are given and the impact of noisy CSIT on the ergodic capacity is examined.
