Abstract:
1. A method of estimating frequency offset of a received signal in a terminal apparatus operating in a wireless communication system, the method comprising: a) determining a phase change between a first and a second reference symbol of the received signal, wherein a time distance t between the first and the second reference symbols is associated with an observation frequency f such that f=1/t; b) determining a preliminary frequency offset Δf based on the determined phase change, wherein the preliminary frequency offset Δf forms a frequency offset hypothesis Δf c) decoding at least a part of the received signal with application of the frequency offset hypothesis Δf d) determining whether the decoded signal is a successful decoding, if the decoded signal is a successful decoding, determining the frequency offset hypothesis Δf if the decoded signal is not a successful decoding:
