1. A method for processing a plurality of signals, the method comprising: receiving one or more observations characterizing a wireless channel; wherein the one or more observations correspond to one or more Orthogonal Frequency Division Multiplexing (OFDM) pilot symbols; performing a channel estimation to determine a probabilistic channel model for the wireless channel, wherein the channel estimation comprises numerically updating one or more multipath gain estimates and one or more multipath delay estimates based on the one or more received observations and a probability distribution associated with the probabilistic channel model; determining a relative change in the multiple path gain estimates and the multipath delay estimates; terminating the updating when the relative change falls below a pre-determined threshold; and processing the plurality of signals using the probabilistic channel model.
