METHOD FOR IMPROVING THE HF BAND LINK ESTABLISHMENT USING A BROADBAND CAPABILITY

摘要

A method for improving the HF band link establishment in a communication system including one or more transmit terminals and one or more receive terminals, at least one of the terminals having a broadband capability, comprises the following steps: creating call bands and listening bands according to the broadband transmit and/or receive capabilities, the minimum number of bands being suitable for covering the entire frequency plan; minimising the number of bands and then maximising the number of frequencies in each of these bands of size B; distributing the bands Bi in time by arranging the bands in descending cardinal-value order, and allocating a frequency fj to each band Bi; transmitting/receiving in broadband mode, by checking that the selected transmit frequencies are not already in use.

1. A method for improving the HF band link establishment in a communication system including one or more transmit terminals or calling terminals and one or more receive terminals or called terminals, at least one of the calling or called terminals having a broadband capability, comprising at least the following steps:
creating call bands and listening bands according to the broadband transmit and/or receive capabilities, the number of frequencies being known, the minimum number of bands being suitable for covering the entire frequency plan, minimising the number of bands and then maximising the number of frequencies in each of these bands Bi of size B, distributing the bands Bi regularly in time in order to minimise the intermediate listening time between two frequencies, at available temporal positions close to a regular subdivision, and allocating a frequency fj to each band Bi in order to define a standard frequency plan for the operation of the system, transmitting/receiving in broadband mode, by checking that the selected transmit frequencies are not already in use.
