Abstract-- Communication over a discrete time-varying Rician
fading channel is considered, where neither the transmitter nor
the receiver has the knowledge of the channel state information
(CSI) except the fading statistics. We provide closed form
expressions to the mutual information under both average and
peak input power constraint when its distribution is complex
Gaussian. The results are compared with the existing capacity
results showing the importance of the perfect CSI at the receiver
at moderate and high signal to noise ratio (SNR). Furthermore,
we show that the peak input power constraint gives better mutual
information compared to the average power constraint input in
Rician fading. Also, we show the information loss with a Gaussian
