Abstract :
A model for multi-band orthogonal frequency division multiplex (MB-OFDM) interference on in-band broadband uncoded QPSK receivers is provided. Multi-band OFDM results in periodic gated noise with power scaled to equal the total power of AWGN over the entire hop time. Since MB-OFDM can have high peak-to-average power (PAP), its impulsive characteristics are captured by the model as a function of the hop depth. Based on the proposed model, it is shown that MB-OFDM is a more harmful interference than ungated AWGN for the same effective isotropic radiated power (EIRP).
