摘要：
Recently, OFDM modulation schemes have been used in various applications. The influence of impulsive noise in the channel is a problem in OFDM. Impulsive noise is often found in man-made noise and is characterized by short time widths and very high amplitudes. Sources of the noise include discharge noise from power lines and switching noise from electronic equipment. Since Impulsive noise has a wide frequency range, it affects all OFDM carrier waves. Therefore, the influence of impulsive noise in the receiver must be reduced. Time Sample Replacement scheme has been proposed as a method for reduction of the influence of impulsive noise. The effectiveness of Time Sample Replacement scheme in OFDM systems employing Non Uniform QAM (NU-QAM), which has been proposed as a new modulation scheme for the next generation, is evaluated.
