... . Then, the wavelet transform is used for calculating the current and voltage service. This approach is based on compensating the zero traveling waves, avoiding low frequency interference generated sequence voltage injected by the SSSC. Although this by the system and the SSSC. Finally, by using reflectometry method was proposed initially for fault detection ...

... Number 2, 2015 consists of several echoes, each displaying the same shape as the transmitted signals, but attenuated and corrupted by noise and false arrivals, including interferences, reflexions by grains, etc. A cross-correlation between the transmitted, in our case, the stepped frequency signal, and the received signals will contain local ...

... in PLC MIMO system are performance and computational complexity. V-BLAST, restored with the obtained detection matrix. The proposed naturally a kind of ZF method, can cancel interference method does not require channel estimation and has low computational complexity. The simulation results show that the between transmitted signals from two different antennas and proposed method has ...
