Consider a channel as a variable filter which cuts off some energy from 
the spectrum of the signal. From here you can find the average loss of 
power of the signal due to fading. This gives you the ideal lower bound 
for the optimal ML demodulator.

Hi,
      I would like to derive the ML equalizer lower bound for frequency
selective fading channels , when the channel is modeled as FIR tapped
delay line with  complex Gaussin random variables as channel tap gains.
 I am not sure, whether there exisists a bound for this?
Any help in this is highly appreciated.
