摘要： The present invention relates to a method and a system for providing a local private broadcasting service with a mobile terminal. The system for providing a local private broadcasting service with the mobile terminal according to the present invention comprises a broadcasting mobile terminal; a viewing mobile terminal; and a broadcasting relay device which relays a broadcasting content to be streamed down in real time from the broadcasting mobile terminal to the viewing mobile terminal placed in a predetermined broadcasting service area centering on a position of the broadcasting mobile terminal based on a movement of the broadcasting mobile terminal. Thus, the present invention provides a method and a system for providing a local private, broadcasting service through which a mobile terminal user performs a private broadcasting and which has a limited, predetermined broadcasting transmission area based on a position of a broadcasting mobile terminal.

摘要： An apparatus for reducing PAPR (Peack to Average Power Ratio) in an OFDM (Orthogonal Frequency Division Multiplexing) system includes: an IFFT (Inverse Fast Fourier Transform) unit for performing an IFFT on an input data stream modulated using a specific constellation to generate time-domain signals; a time-domain clipping unit for performing a time-domain clipping on the time-domain signals at a clipping level determined by characteristics of the time-domain signals; an FFT (Fast Fourier Transform) unit for performing an FFT on the clipped time-domain signals to generate frequency-domain signals; and a frequency-domain clipping unit for performing a frequency-domain clipping on the frequency-domain signals. The time-domain clipping reduces in the OFDM system, and the frequency-domain clipping reduces distortions generated by the time-domain clipping.
