    Abstract: An operation method with fingerprint recognition, an apparatus, and a mobile terminal relate to the field of communications technologies, where the method includes obtaining a fingerprint input by a user's finger at a preset position on a touchscreen of the mobile terminal, displaying at least one shortcut when the fingerprint matches a preset fingerprint and a duration of the finger at the preset position on the touchscreen exceeds a predetermined duration, detecting a sliding operation input by the finger using the preset position as a start position, determining a first shortcut from the at least one shortcut according to a direction of the sliding operation and running the first shortcut. Thereby reducing operation duration, and improving operation efficiency.

    Abstract: The present invention relates to a method in a wireless communication system for determining whether an active eavesdropper is interfering in transmissions on a radio channel from a transmitter to a receiver, the method comprising the steps of: estimating, by said transmitter, a first effective channel gain of said radio channel at said receiver; estimating, by said receiver, a second effective channel gain of said radio channel at said receiver; and determining whether an active eavesdropper is interfering in the transmissions by comparing said first and second effective channel gains. Furthermore, the invention also relates to a method in a receiver, a receiver device, a computer program, and a computer program product thereof.

    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.

    Abstract: Receiver and method in a receiver, for estimating a normalised frequency offset between a transmitter and the receiver in a wireless communication system, based on Orthogonal Frequency Division Multiplexing, OFDM. The method comprises receiving a first pilot signal (yr1) and a second pilot signal (yr2) from the transmitter; computing a Karhunen-Loeve approximation λK(φ), up to any finite order K of a log-likelihood function λ(φ), based on the received pilot signals (yr1, yr2); and estimating the frequency offset by calculating a maximum value of the computed Karhunen-Loeve approximation λK(φ).
