    Abstract: A receiving device including a receiver configured to receive a communication signal (CS) in a current time frame, and a processor configured to determine a set of candidate Control Channels (CCHs), determine a decoding order for the candidate CCHs in the set, decode at least one candidate CCH in the set according to the decoding order, compute a possible Radio Network Temporary Identifier (RNTI) for the decoded candidate CCH, compute a metric value (MV) for the decoded candidate CCH, the MV provides an indication when the decoded candidate CCH might be an actual CCH, determine when the decoded candidate CCH is an actual CCH based on the computed possible RNTI and the MV, derive control information (CI) from the decoded candidate CCH when the decoded candidate CCH is determined as an actual CCH, and cancel or suppress interference in the CS based on the derived CI.

    Abstract: Embodiments of the present invention disclose a method and an apparatus for transmitting a CPRI signal by means of a coaxial line. The method includes: converting a Common Public Radio Interface CPRI signal sent by a sending end into a parallel data stream; extracting valid data from the data stream by performing frame parsing; and converting the valid data into a transmittable analog signal, modulating the analog signal to a specified frequency, and sending it to a receiving end by means of a coaxial line. The present invention applies to transmission of a CPRI signal by means of a coaxial line.

    Abstract: The present disclosure relates to an iterative method for estimating covariance matrices of communication signals comprising a) computing a reference symbol covariance matrix estimate (k,l); b) inputting said reference symbol covariance matrix estimate (k,l) to a detector or a decoder in a first iteration, and thereafter inputting the covariance matrix estimate output from e) to the detector or the decoder in subsequent iterations to obtain an updated demodulated or decoded communication signal for each iteration; c) inputting the demodulated or decoded communication signal to a symbol generator; d) computing an updated data covariance matrix estimate (k,l) for each iteration based on data symbols of said regenerated communication signal; e) combining said reference symbol covariance matrix estimate (k,l) and said updated data covariance matrix estimate (k,l); and f) forwarding said covariance matrix estimate output to the detector or decoder in b) to obtain the updated demodulated or decoded communication signal for each iteration.
