Abstract: Through the illustration of frequency domain of orthogonal frequency division multiplexing system, the construction method of complex baseband signal for LTE orthogonal frequency division multiplexing system based on LTE standard is analyzed and proposed to corroborate the proposed method, and a lower complexity engineering implementation method of complex baseband signal for orthogonal frequency division multiplexing system is also presented. An experimental environment based on Matlab, WinIQSim and radio frequency(RF) signal source is constructed and the proposed method is proved correct. 

Key words: orthogonal frequency division multiplexing(OFDM), complex baseband signal generation, frequency domain
