Webfeatures of the practical slowly-varying fading channels. In a block-fading channel a codeword spans a ﬁnite number B of independent fading blocks. As the channel relies on particular realizations of the ﬁnite number of independent fading coefﬁcients, the channel is non-ergodic and therefore not information stable [3], [4]. how to say timidity
