Abstract
A method and system is provided for estimating a first wireless communication channel (FWCC) transmitting a data stream from a first antenna system (FAS) to a second antenna system (SAS) in a telecommunication system, the telecommunication system having a second wireless communication channel (SWCC) for transmitting data from the MT to the antenna. First, one or more characteristics of the SWCC (SWCC Characteristics) are analyzed based on the data stream received by the antenna system from the MT. From the data stream received, an initial condition of the FWCC is also extracted. One or more characteristics of the FWCC (FWCC Characteristics) are predicted based on the SWCC Characteristics and the extracted initial condition, wherein analyzing the SWCC Characteristic and estimating the FWCC Characteristics relying on the feature that the data stream has a plurality of data segments whose Doppler frequencies are close to each other to an extent that the Doppler frequencies are deemed as the same for the purpose of analyzing the SWCC Characteristics.
