Analysis of Outage Probability and Average Signal Power of Two Independent Block Fading Channel for a SISO System

This paper deals with the design of a new system where the channel is subjected to a more generalized scenario by considering two-independent block fading (L = 2). Each block undergoes different fading characteristics for a particular time interval. This time interval is the coherence interval such that the channel coefficient is fixed during a fading block, and statistically independent from one block to another. The main focus of this work is to derive performance measures, such as outage probability and average signal power for Rayleigh, Nakagami, and Weibull fading channels. Once the mathematical expressions are derived, attention is focussed to obtain numerical results for L = 2 by plotting analytical graphs for the obtained expressions and are observed with proposed system parameters like average fading channel power and signal-to-noise ratio (SNR) in the case of a Rayleigh fading channel, Nakagami fading parameter m, fading power Ω, and SNR in the case of a Nakagami fading channel, and Weibull fading parameters k and λ in the case of a Weibull fading channel. The proposed system can thus be evaluated and the amount of degradation can be measured.
