My recent paper in IEEE Transactions on Communications (PDF):
X. Jin, A. W. Eckford, and T. E. Fuja, "LDPC codes for non-coherent block fading channels with correlation: Analysis and design," IEEE Trans. Commun., vol. 56, no. 1, pp. 70-80, Jan. 2008.
The paper is about density evolution and code design for LDPC codes on block fading channels, where the channel coefficients are correlated between blocks. This is a realistic model for OFDM or frequency hopping spread spectrum.
