Abstract

Many data transmission systems have an internal resource which can be used to enhance noise immunity of transmission. In this article opportunities of increase of immunity to interference and frequency-selective fadings, consisting in redundancy of frequency resource in the form of frequency diversity will be examined ([1-3]). If the transmission is realized under conditions of multipathing, then the choice of way of using the redundancy is depended on the bandwidth of the signal. By transmitting broadband signals it is necessary to take into account the phenomenon of multipathing, which occurs when a great number of over-reflectors of signal is present. By tropospheric or ionospheric wave propagation there is Inhomogeneity of electrophysical properties of the medium. In urban conditions multipathing appears due to the variety of urban relief with lots of metal fragments.
