through the plurality of transmit feeds in accordance with the weighting procedure and subsequent interference at the receiver location, wherein the second signal comprises a waveform component for each of the plurality of transmit feeds. In other words, this method relates to estimating a channel vector (channel state vector) in a wireless MISO (satellite) communication system employing precoding, wherein a receiver receives a signal comprising a plurality of waveform components, each waveform component being subdivided into frame units, wherein each frame unit has a first field that is not subjected to precoding and that indicates a start of the respective frame unit and one or more second fields and that each comprise a predetermined pilot sequence n a preferred embodiment, the frame unit comprises two or more second fields, and the steps described below are applied to said two or more second fields. After reception of the signal, the signal is sampled in a sampling unit (not shown in Fig.3) to obtain a sequence of samples corresponding to the received signal. A first frequency estimation (coarse frequency estimation) of the carrier frequency of the received signal is performed. The coarse frequency estimation may be performed for instance by the algorithm proposed in Kim et al. in "Robust frame synchronization for the DVB-S2 system with large frequency offsets," lnt. J. Satell. Commun. Network., vol. 27, no. 1, pp. 35-52, 2009, which is hereby incorporated by reference. Of course, also other algorithms for performing the coarse frequency estimation are feasible, such as by a quadri-correlator as proposed in DAndrea, A.N.; Mengali, U., "Design of quadricorrelators for automatic frequency control systems", 1EEE Transactions on Communications, vol.4l, no.6, pp.988-997, Jun 1993, which is hereby incorporated by reference. This step is performed at the frequency acquisition unit 250. Matched filtering is performed in order to increase the SN1R of the received signal. Therein, the matched filter is determined based on the frequency estimated in the frequency acquisition unit 250. Methods for performing matched filtering are known in the art. This step is performed in the matched filter 251. Frame synchronization is performed by searching the received signal for the known sequences of symbols (codewords) indicating the start of the super-frames (frame units) in the respective beams (i.e. respective waveform components) n other words, a start of a frame unit of a waveform component, e.g. waveform component m, is determined by searching (using a correlator), in the received signal, for a first field indicating the start of the respective frame unit. The received signal contains, in each waveform component, first fields indicating the starts of respective frame units, wherein the first fields in different waveform components are mutually orthogonal. Accordingly, the start of a frame unit in a given waveform component can be determined by correlating the received signal with a known codeword corresponding to the content of the first field of the frame units of the given waveform component.
