Abstract: A method for processing a plurality of signals may include receiving one or more observations characterizing a wireless channel, performing a channel estimation to determine a probabilistic channel model for the wireless channel, and processing the plurality of signals using the probabilistic channel model. The channel estimation may include 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.

Abstract: A method for processing one or more received radio signals is provided. The method may include performing a channel estimation of a transmission channel for at least a portion of the one or more radio signals received, to identify at least one soft channel parameter representing a channel impulse response of the transmission channel, and identifying at least one soft intercarrier interference parameter representing an interference for the one or more radio signals received using a first frequency carrier. The interference is caused by the one or more radio signals received using a second frequency carrier. The method may further include detecting soft data from the one or more radio signals based at least on the at least one soft channel parameter and the at least one soft intercarrier interference parameter.

The adjustable connection device has two notched tabs that are arranged respectively on either side of one of the shells, each notched tab co-operating in adjustable manner with a respective adjustment housing, arranged correspondingly on either side of the other of the shells, each notched tab having adjustment teeth to adjust the position of the shells one relative to the other, and locking housings to lock the position. The locking housings are oriented transversally relative to the adjustment teeth.
