Abstract: The present invention relates to a method for estimating parameters of a blind block interleaver and a channel coding, capable of estimating and restoring the parameters of the interleaver such as the cycle, type and matrix size of the interleaver by analyzing received unknown signals and estimating the channel coding. An apparatus for estimating parameters of a blind block interleaver and a channel coding according to an embodiment disclosed in the present specification comprises: a data generator for generating an arbitrary data combination used in an analysis by generating a random bit and performing an arbitrary channel coding and interleaving process on the random bit; and an estimator for constructing one matrix on data to be analyzed practically and the arbitrary data for the Gauss-Jordan elimination operation, performing the Gauss-Jordan elimination operation on the constructed matrix, detecting the ratio of ones within the data resulted from the Gauss-Jordan elimination operation, and determining, as an estimated value of the interleaver and the channel coding, a channel coding type, an interleaver type and a matrix size of a data combination having the lowest ratio of ones among arbitrary data combinations having the ratio of ones lower than a threshold.

Abstract: PURPOSE: A drive apparatus of a sensor capable of precise stabilization for all directions is provided to guarantee the precise stabilization of a drive unit since the drive unit is driven by three axes. CONSTITUTION: A drive apparatus(200) of a sensor capable of precise stabilization for all directions comprises an outer azimuth angle rolling unit(210), a closing member(220), an inner azimuth angle rolling unit(230), and an elevation angle rolling unit(240). The sensor is installed inside a housing(201). The outer azimuth angle rolling unit is connected to the housing. The outer azimuth angle rolling unit rotates the housing around a principal axis. The closing member is arranged between the outer azimuth angle rolling unit and the housing in order to seal the inside of the housing. The inner azimuth angle rolling unit rotates the sensor around the principal axis in a specific rotation range. The elevation angle rolling unit rotates the sensor around a second axis vertical to the first axis.
