Abstract :
Several wireless systems and networks share the same or contiguous frequency bands to provide wideband connectivity. Due to the different channel access techniques, the related communication signals are often transmitted, at the same time, over frequency intervals partially or fully overlapping to one another. In such cases, classical approaches either in the frequency or joint time-frequency domain fail in evaluating the power spectrum of each signal, thus preventing relevant measurement information, like channel power, occupied bandwidth and carrier frequency, to be accurately gained.
