In the wireless systems, the signal propagation is affected by path loss, slow fading (shadowing), and fast fading (multi‐path fading). As we know, there is a correlation between communication channels in the real radio environments. This correlation is defined by the correlation between their...
Fading refers to variation in signal strength with respect to time as it is received at the antenna from the transmitter at distant end. The variation can be result of communication channel between the transmitter and receiver. The figure depicts both fast fading and slow fading amplitude versus ...

, we pursue an energy-efficient video communication solution through joint video summarization and transmission adaptation over a slow fading wireless channel. ... Z Li,F Zhai,AK Katsaggelos - 《Eurasip Journal on Advances in Signal Processing》 被引量: 60发表: 2008年 Video summarization for energ...
The topic of this study is the outage behavior of multiple-antenna slow fading channels with quantized feedback and partial power control. A fixed-rate communication system is considered. It is known from the literature that with error-free feedback, the outage-optimal quantizer for power control...

We show a large increase in the capacity even for small Rician factors. A Rician fading is usually encountered when the mobile is close to the base station and thus the path-loss exponent can be less than four. Thus, we investigate the effect of changing the path-loss exponent value on ...
