We propose a new analytical approach to evaluate
the average packet error rate (PER) of a conventional packet
transmission system over a quasi static fading channel, by
presenting an integral inequality lemma. The basic idea of the
approach is that, given the PER for the AWGN channel as a
function of signal-to-noise ratio (SNR), the average PER over
Rayleigh fading channel can be generally upper bounded by a
quite simple inequality, i.e.,1-¿¿¿(-¿0/¿), for both coded and
uncoded schemes, where ¿0, defined by an integral expression,
corresponds exactly to the inversion of coding gain; and this
bound is tight in the high SNR region or for long packet systems.
We further apply the integral inequality to ext
