Abstract:
Disclosed are apparatus and a method for monitoring a bus state in a system on chip (SoC). The apparatus for monitoring the bus state in the SoC according to the present invention includes a data obtaining unit which obtains bus state data by using a bus protocol in the SoC; a data substituting unit which obtains output data by substituting the bus state data from a bus protocol type in the SoC to a software source code type; a data storage unit which stores the output data in a register; and a data providing unit which provides the output data according to the request of a main processor.
Abstract:
PURPOSE: A method for operating a transmitting device in a wireless communication is provided to reduce an I/Q imbalance processing load in a transmitter by preventing the I/Q imbalance of the transmitter. CONSTITUTION: First and second sinusoidal signals are generated (S210). The gain difference and the phase difference of the first and second sinusoidal signals are detected (S220). The I/Q imbalance of a transmitter is compensated based on the detected gain and phase differences (S230). Signals with the compensated I/Q imbalance are modulated and are transmitted to another wireless terminal (S240). The first and second sinusoidal signals are carrier signals in an in-phase axis and a quadrature phase axis.

PURPOSE: An intelligent base station using a TV(TeleVision) idle band is provided to improve accuracy for dividing a TV idle band. CONSTITUTION: A spectrum sensing processing unit(240) processes a spectrum sensed TV idle band. A wireless transmission and reception unit(250) transmits and receives a signal to the set TV idle band. A control unit(260) determines the TV idle band by comparing the TV idle band of the TV idle band database with the TV idle band sensed by a spectrum. The control unit sets the wireless transmission and reception unit transmitting and receiving a signal with the determined TV idle band.

Abstract:
PURPOSE: An operation method of a wireless communication base station is provided to offer the security of a physical layer through an additional device such as an additional antenna and a signal generation module for preventing the hacking of base stations based on a wireless communication network. CONSTITUTION: A base station discriminates the security of data transmitted to a user terminal(S110). The base station generates a signal for preventing the hacking according to the discrimination result(S120). The base station transmits the signal for the hacking and the transmitted data(S130). The signal for the hacking is generated for being orthogonal with the channel information of the user terminal. [Reference numerals] (AA) Start; (BB) End; (S110) Discriminate the security of data transmitted to a user terminal; (S120) Generate a signal for preventing hacking; (S130) Transmit the signal for preventing hacking and the data transmitted to the user terminal together
