A Semi-Analytical Approximation to the Block Error Rate in Nakagami-m Block Fading Channels
One of the main performance measures of any packet based communication
system is the success rate of the packets. A packet
is successfully received if the arrival of the packet is detected correctly,
header is received successfully, and payload is decoded without
errors. At the moment, the probability of failure to decode the
payload, i.e., block error rate (BLER), is often obtained by numerical
methods, such as Monte-Carlo simulations due to shortage of
analytical expressions for BLER.
In this work, an approximation method for estimating the BLER
in Nakagami-m block-fading channels is proposed. Furthermore, an
analytical expression with a single parameter is derived for Nakagami-
m channels. This parameter can be obtained by single simulation
at a single signal to noise ratio (SNR) in Rayleigh fading channel.
Our simulation results demonstrates that the proposed methods is
highly accurate is estimating the BLER of many important wireless
