Title: Wireless communication method using equalizer in frequency domain
Inventor: KIM YONG HUN
IPC: H04N7/015
Filed: 2001-11-19
Abstract: PURPOSE: A method for wireless communication using a frequency domain equalizer is provided to prevent drop in a frequency use efficiency due to the environmental change, and realize stable operation characteristics. CONSTITUTION: A symbol mapper maps data symbols. A preamble and data frame including null data is generated. A pulse shaping part shapes the frame in a time arbitrary shape. A high frequency transmitter and an antenna transmit the shaped frame wirelessly. A high frequency receiver receives the frame of high frequency from the high frequency transmitter. A matched filter receives an output signal of the high frequency transmitter for match-filtering the output signal. A frame detector receives an output signal of the matched filter for detecting the original frame generated by a frame generator. The detected frame is Fourier-transformed in an inverse direction. An equalizer equalizes the Fourier-transformed frame. A fast Fourier transformer quickly Fourier-transforms the frame. A symbol demapper receives the Fourier-transformed signal for mapping the symbols in the original shape. A decoder reconstitutes the symbols to obtain the original data.
