... 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 ...

... must vacate the spectrum immediately and transfer their communications to II. RELATED WORK another idle spectrum. Thus, a spectrum handoff scheme is To prevent secondary transmission from interference by required to maintain the current transmission with minimum appearance of PUs, the authors in [6] propose a spectrum selection rule by using only one sub-band ...

... power consumption and the benefit A major performance-degrading factor is the noise floor, of multipath energy capture. However, this technique is very sensitive to noise and channel interference. To minimize this which is aggravated for UWB signals with a large time- drawback, optimizations have been proposed with respect to bandwidth product [5] ...

... . 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 ...
