bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...

A general approach is presented for analyzing the performance of digital signaling with multichannel reception on correlated fading channels . The approach is based on a complex Gaussian model for the joint distribution of the fading on the multiple channels, and recent results on the unified performance analysis of digital signaling on fading channels using an alternative representation of the...

A general approach is presented for analyzing the performance of digital signaling with multichannel reception on correlated fading channels. The approach is based on: i) exploiting the complex Gaussian model for the joint distribution of the fading on the multiple channels; and ii) applying recent results on the unified performance analysis of digital signaling on fading channels using alterna...
