	Interference suppression in a MLT based spread spectrum system with digital beamforming

英文摘要	In this paper, we improve the traditional expanded time and frequency OFDM (ETF-OFDM) system by using Inverse Modulated Lapped Transform (IMLT)/Modulated Lapped Transform (MLT) instead of Inverse Discrete Fourier Transform (IDFT)/Discrete Fourier Transform (DFT) in the OFDM modulation/demodulation part, respectively. For further interference suppression, we adopt the digital beam forming scheme at the transmitter to null-steering the jammings. Simulation results show that the proposed system has better anti-jamming performance than the conventional DFT-based system. ? 2010 IEEE.; EI; 0
