Rise Noise-Immunity of Mobile Communication in Lognormal Fading by Interconnecting Interrupt Communication with Diversity Receives


M. N. Andianov

Diversity reception reduces influence of fading communication channel. When number branches in diversity reception are very big, we can’t to achieve considerable win using interrupted communication. However in mobile communication are application small of number branches. In this case effect of using interrupted communication can be considerable. In addition this application increase coefficient of use radio line. This coefficient mean relationship time of transmit data to common time of communication session. In this work function has obtaining: probably density for relationship signal to noise; coefficient of use radio line using M–multiply diversity reception with ideal auto-select independent lognormal fading. It shows that for said lognormal fading diversity reception reasonable implement using angle-diversity, not space-diversity. Formula has obtaining for probably of mistakes interconnecting interrupted communication with diversity reception union of branch using algorithm auto-select on define relationship signal to noise in undisturbed environment ( ) for fixed threshold ( ) and threshold equal average relationship signal to noise ( = ). Made compare said mode of receive and diversity reception union of branch using algorithm auto-select without interrupted communication.
