A Communication System with Wavelet Packet Division Multiplexing in an Environment of White Gaussian Noise and Narrow-Band Interferences*
نویسندگان
چکیده
The performance of a communication system with wavelet packet division multiplexing in an environment of white Gaussian noise and narrowband 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 220 V.

Performance Comparison of Wavelet Packet Transform (WPT) and FFT- OFDM System Based on QAM Modulation Parameters in Fading Channels
Orthogonal Frequency Division Multiplexing (OFDM) has been widely adopted in many applications due to its good spectral performance and low sensitivity to impulse noise and multipath channels. It has been widely adopted and standardized in many applications today. It is well known in OFDM that a cyclic prefix (CP) is appended to each symbol in order to mitigate the effect of Inter-Symbol-Interf...
متن کاملHigh-speed Power Line Communication System based on Wavelet OFDM
Recently, the demand of high-speed network in home is increasing. PLC (Power Line Communication) is expected as one method of realizing it. OFDM is one of the methods, which realizes high-speed PLC. But the minimum stopband attenuation of OFDM modulation is only -13dB. It indicates that OFDM subchannels are not spectrally isolated, therefore OFDM is sensitive to the locations of narrow band int...
متن کاملPerformance of wavelet packet-division multiplexing in impulsive and Gaussian noise
Wavelet packet-division multiplexing (WPDM) is a high-capacity, flexible, and robust multiple-signal transmission technique in which the message signals are waveform coded onto wavelet packet basis functions for transmission. In this letter, we derive an expression for the probability of error for a WPDM scheme in the presence of both impulsive and Gaussian noise sources and demonstrate that WP...

The orthogonal frequency division multiplexing is used in wireless communication due to high data rate. OFDM are robustness against multi-path fading, frequency selective fading, and narrow band interference. Wavelet analysis has strong advantages over fourier transform and also allows time-frequency domain operation with flexibility. Wavelet is applied in various fields of wireless communicati...
