is the channel transfer matrix which is also the polarization
matrix, and w/E: is a normalization factor. The polariza-
tion matrix describes the degree of suppression of individual
co- and cross-polarized components, cross correlation, and
to an order of magnitude.

Part I: Statistical description of the wireless channel
Large-scale fading take place in an environment with tall structures. The signal is likely to be multiple
reflected or scattered before taking multiple paths to the receiver.
(2) Linear Distortionless System
The input and the output have identical waveshapes within a multiplicative constant. A delay output that retains
the input waveform is also considered distortionless y (t ) k x(t t d )
