    摘要: According to one embodiment, a method for repetitive transmission using a plurality of sub-carriers includes: preparing a symbol to be transmitted using the plurality of sub-carriers within a single time domain unit; repeating the symbol a predetermined number (N) of times; applying a corresponding one of N different cyclic shift values to each of the N repeated symbols to be transmitted using the plurality of sub-carriers within the single time domain unit; performing an IFFT (Inverse Fast Fourier Transform) on each of the N repeated symbols to which the corresponding one of the N different cyclic shift values is applied; and transmitting the N repeated symbols on which the IFFT is performed using the plurality of sub-carriers.

    摘要: An apparatus and method for authenticating a telematics terminal are disclosed to receive a first telematics service based on inputted user authentication information and then easily receive a second telematics service based on the inputted user authentication information. The method for authenticating a telematics terminal in a vehicle including: storing user authentication information inputted to receive a first telematics service through a mobile communication network; and requesting a second telematics service to an information providing center through the mobile communication network based on the stored user authentication information.
