Abstract
The present paper describes a novel telecommunication facilities based on the currently available microwave integrated teleradio information system, which, in abbreviated form, will henceforth be referred to as MITRIS. This technique is intended for transferring digital data in the range of 11.7-12.5 GHz (in particular , it is likewise destined for distributing TV programs and internet-wide services). The above system is operative using the combined (two-level) modulations, specifically, the primary one is related to quadrature-amplitude keying, the secondary is frequency-dependent.
KEY WORDS:wireless access, telecommunication system MITRIS, antijamming, spectral efficiency, spectrum of signal, two-level modulation
