Alternative Approach for Combination of Fingers in Underwater Acoustic Communication
International Journal of Distributed Sensor Networks, 2016 An underwater acoustic communication channel is time varying and has multipath propagation with bottom and surface reflection. A rake receiver has time diversity effects in multipath propagation environments.

Maximum likelihood time-of-arrival estimation using antenna arrays: Application to global navigation satellite systems [PDF]
, 1998 The problem of estimating the time-of-arrival (TOA) of a known signal in the presence of interferences and multipath propagation is addressed. This problem, is essential in high precision receivers of the Global Navigation Satellite Systems.

Multipath propagation in line-of-sight links
Electronics Letters, 1979 Using a classical model, and adding two complementary propositions, it is possible to obtain a general method for calculating the fading distribution laws on line-of-sight links of indifferent lengths undergoing multipath propagation. In particular, it is shown that the conventional empirical d3.5 power law gives a rough approximation in a very limited
