First, the probability density functions (PDFs) of the instantaneous signal to noise ratio for a DB SIMO system in the eta-mu and the lambda-mu fading conditions. Then, the closed-form expressions of the effective rate (ER or effective capacity) for a SIMO network are derived. In addition to this, asymptotic ER expressions for the considered SIMO network are proposed. The analytical capacity expressions with different transmission policies such as optimal rate adaptation with constant transmit power, optimal simultaneous power and rate adaptation, channel inversion with fixed-rate (CIFR), and truncated channel inversion with fixed-rate are obtained for the SIMO network. Furthermore, the capacity expressions with CIFR policy for DB SIMO communications over the eta-mu and the lambda-mu fading channels are derived by using the proposed PDFs. Finally, the amount of fading expressions for SIMO networks over the eta-mu and the lambda-mu fading links are proposed by employing the elementary functions. The proposed analytical expressions provide to establish different radio propagation scenarios by adjusting eta, lambda or mu parameter. To confirm the accuracy of our analysis, the proposed analytical expressions are verified via exact simulations. (C) 2020 Elsevier Inc.
