What is it about?
The usage range of nowadays wireless communications become wide, all of the develop applications uses wireless communication which improve the mobility and improve the mobility of the network subscribers. As known that the antenna diversity scheme developed from “SISO” to “MIMO” that has a maximum capacity and ability to improve the communication quality with a good shields among the fading effects and other impairments. In this research work study and analysis to the antenna systems and antenna schemes was done taking into consideration the central antenna system and the distributed antenna system “CAS” and “DAS”. A Matlab simulation was developed to test antenna configuration system in term of effeteness of fading channel while using different modulation order.

Why is it important?
Noise are indiscriminate inconstancy at electrical signal, a distinctive to totally electronic circuits.  Fuss created in electronic devices differ very also created by some various effects. Thermic noise are inescapable on non-nil temperature (view inconstancy - dispersion theory), although other kinds rely generally at device pattern (similar shot noise,   that wants a steep possibility partition) else industrialization quality then semiconductor impairment, identical conduct fluctuations, inclusive 1/f noise. Noise are an error neither undesirable random inconvenience of beneficial data signal. At communication systems, the noise are summary of undesirable else annoying energy from normal and occasionally man-made sources. Noise are, whilst, normal distinguished from interference, [a] to case that “signal-to-noise ratio” (SNR), “signal-to-interference ratio” (SIR) also “signal-to-noise plus interference ratio” (SNIR) measurements. Noise as well normally distinguished from deformation that are undesirable methodical change of signal waveform through the communication preparation, for epitome at signal-to-noise and deformation ratio (SINAD) and “total harmonic distortion plus noise” (THD+N).
