Abstract :
In this paper, the effect of radar-induced electromagnetic interference (EMI) on a WiMAX base station receiver is investigated through the use of MATLAB models. The three types of radar pulses investigated include: a short, wideband, chirp pulse; a long, narrowband, chirp pulse; and a long, sinusoidal pulse. The benefits of superimposing these pulses in the guard interval and/or guard band of the WiMAX waveform are explored.
