Principles of Data Transmission Network Development in the Medium Wave Range in the Waters of the Northern Sea Route

The work shows, that in developing transmission network for data transmission in the waters of the Northern Sea route it is expediently to use medium-wave band at the expense of more steady telecommunication line because of lack of spatial wave in near-field zone. Types of modulation and signal-code designs for down-link and up-link were determined. Also it was established that using amplitude-phase modulations with block turbo code, it provides the best spectral and energy efficiency for down-link and frequency-shift signal for up-link is efficient.
