Abstract :
The generalized Duman & Salehi (see IEEE Trans. on Communications, vol.46, no.6, p.717-23, 1998) bound is used in the realm of mismatch decoding metric for random and deterministic codes. In the random coding case with a proper restriction of the random ensemble, the technique reconstructs the Csizar-Korner-Hui lower bound. For deterministic codes, the bound is given in terms of the distance spectrum of the code and the results are demonstrated for fading channels with an estimate of the fading channel state information
