PROCEDE ET SYSTEME DE COMMUNICATIONS ADAPTATIVES EN BANDE HF |
摘要 |
<p>The method involves determining a useful sub band (310) available for transmission in high frequency band based on criteria e.g. number of frequencies allocated to user based on a plan (301) of allocation of frequencies and physical availability of the sub band evaluated based on prediction of disturbances induced on signal by reflections from ionospheric layers. A set of frequency channels with identical width is selected (313) in the sub band based on the plan and connection quality of each channel. The channels of a signal respecting a high frequency wave are simultaneously transmitted. An independent claim is also included for a high frequency band communication system comprising a high frequency transmitter and a high frequency receiver.</p> |
