TLDR
In this paper, the authors proposed a method for computing a channel transfer function (800, 900, 1000, 1100) between the transmitting user device at each of the plurality of receiving antennas by computing a simulated received pilot signal for each receiving antenna.Abstract:
A method and device in a communication system (100) including a receiver (201) having a plurality of receiving antenna (101) for receiving a plurality of information burst (400) transmitted by at least one transmitting user device where the information bursts contain a number of data symbols (430) and a pilot symbol sequence (420) of content known at both the transmitting user device and the receiver. The method provides for computing a channel transfer function (800, 900, 1000, 1100) between the transmitting user device at each of the plurality of receiving antennas (101), by computing a simulated received pilot signal for each receiving antenna, computing an error signal between the simulated received pilot signal and the received pilot symbol sequence, computing a channel modeling sequence, wherein the power of the error signal is minimized, and computing the channel transfer function by weighting predetermined basis functions by the channel modeling sequence.read more
