Abstract:
The performance of a communication system with wavelet packet division multiplexing in an environment of white Gaussian noise and narrow-band interferences is studied. Wavelet packet transforms and their place for generation and detection of communication signals in this paper are examined. They are examined as an alternative of multi-frequency systems and particularly OFDM. The frequency efficiency of such systems is shown. The performance in an environment of additive white Gaussian noise and narrow-band interference is examined. A noise model of the narrow-band interferences is designed according to the ones observed in the power network of 220V.
Keywords: communication system, wavelet packet division multiplexing.
