Statistical Analysis of the Power-Line Channel Noise Characteristics in the Frequency Domain
نویسندگان
چکیده
In this paper we are studying the power line channel noise in the frequency domain. The noise is measured using a spectrum analyzer. The channel noise profile is essential when OFDM is applied. Moreover, noise measurements are statistically processed in order to extract the probability density functions of the noise power for more than 120 different frequencies in the frequency range 1.15MHz-30MHz. The probability density functions of the noise power spectrum density are dominated by the impulsive components of the noise and they could be a useful tool to estimate the capacity of the power line channel when OFDM is applied. Key-Words: -Power-line channel noise-model, OFDM system

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

متن کاملOutput-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data
The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...
متن کاملA Novel Frequency Domain Linearly Constrained Minimum Variance Filter for Speech Enhancement
A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...
متن کاملAnalysis of Planar Microstrip Circuits Using Three-Dimensional Transmission Line Matrix Method
The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...
