Webassumed that the fading process is a Rayleigh fading process. The discrete samples of the Rayleigh fading process have a Rayleigh distribution and are correlated. For generating the Rayleigh fading coe–cients, three diﬁerent methods of random variate generations are used. The model proposed by Jakes [1] is a commonly accepted model of a ... Weband IDD schemes have dealt with quasi-static Rayleigh fading channels or fast Rayleigh fading channels. However, there are very few studies related to the case of block-fading channels with MIMO systems.

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]. Webupper bound to the outage probability of Rayleigh and Rician block-fading channels is proposed in [9], [10]. In this paper, we propose a tight lower bound to the outage probability which can be efﬁciently evaluated for the general Nakagami-m block-fading channel [11]. We also show that the optimal rate-
