Abstract

For wireless packet transmissions, preambles are essential to make packet synchronization function. Impulsive interference not only distorts datum, but also degrades link reliability. To deal with such distortions, a peak-to-average ratio (PAPR) detection is adopted to search impulsive positions and the convolution with the estimated time-domain response is used to recovery the distorted preambles. Simulations of a 2x2 MIMO-OFDM system with RF impairments in frequency-selective fading indicate that the SNR loss is about 2.5 dB sim; 4.6 dB to ensure synchronization working at a signal-to-impulse ratio (SIR) of -10 dB.
