Websystems to accomplish the trade-off between complexity and accuracy [1–7]. The two basic 1D channel estimations are block-type pilot channel estimation and comb-type pilot channel estimation, in which the pilots are inserted in the frequency direction and in the time direction, respectively. The estimations for the block-type pilot arrangement Webboth Rician and Rayleigh fading channels unlike [13] which can only be applied for AWGN channels. • The proposed union bounds for the Rician fading do not contain any binomial coeﬃcients and so their computational complexity is less than the Rician approximation of [2] which is a Taylor series expansion with a binomial coeﬃcient. drap kakiWebDigital Communication over Fading Channels, 2nd Edition Marvin K.

"The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative t… " - Fading channel types
