Performance measures of L-independent block fading rayleigh channel with perfect channel estimation for a SISO system

Abstract

This paper deals with the design of a new system where Rayleigh fading channel is subjected to a more generalized scenario by considering L-Independent block fading, where L= 2, 3, ... Each block undergoes different fading characteristics for a particular time 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. Once mathematical expressions are derived, attention is given to obtain numerical results by plotting analytical graphs for the obtained expressions, and is observed with the proposed system parameters like Signal to Noise Ratio (SNR), average channel power and data transmission rate. Hence, the proposed system can be evaluated and the amount of degradation can be measured.
