    摘要: The present invention provides a display parameter adjusting method and an electronic device employing the method. The electronic device includes a display, a light source and a light receiver. The display parameter adjusting method includes: emitting a light beam to the light receiver by the light source; calculating a turbidity of a location of the display according to a first light intensity of the light beam received by the light receiver, wherein a propagation direction of the light beam emitted by the light source is parallel to a displaying surface of the display, and the location is beneath a water surface; and adjusting the display parameter according to the turbidity.

    摘要: A method comprises determining a first and a second sub-carrier associated with a channel, and multiplying a signal received on the first sub-carrier with a first number to form a first resulting signal. The first number multiplied with a known signal transmitted by a second transmitting node on the first sub-carrier equals a constant value. A signal received on the second sub-carrier is multiplied with a second number to form a second resulting signal. The second number multiplied with the known signal transmitted by the second transmitting node on the second sub-carrier equals the constant value. The second resulting signal is subtracted from the first resulting signal to obtain a signal for which interference from the second transmitting node is suppressed, and the channel is estimated based on the obtained signal.

    摘要: Various examples of the present disclosure describe a random access method and device in a CR system. The method includes: generating, by a base station device, a spectrum handover command, wherein the spectrum handover command comprises random access backoff time parameter information; and sending, by the base station device, the spectrum handover command to a user equipment in a cell to instruct the UE to initiate, during a spectrum handover procedure, a random access procedure using the random access backoff time parameter information. According to the various examples of the present disclosure, the random access backoff time parameter information is carried in the spectrum handover command, so that a random access conflict is suppressed during the spectrum handover procedure of the CR system. A large number of UEs that intensively perform random access on a target working frequency are pre-dispersed in time. As such, the delay and the failure probability of the random access on the target working frequency during the spectrum handover procedure are reduced, and thus the failure probability of the spectrum handover and the service interruption time are reduced, so that the user experience of the CR system is improved.
