There is a relationship between rolloff rate and the needed sensitivity, given by the formula in Figure 3. Since fiber-optic receivers are broadband noise limited, their sensitivity is reduced when bandwidth is any greater than absolutely required. Webdata rate (that is, code rate) of the HF modem in response to changing channel conditi ons (adaptive data rate). This capability requires remote control of the HF modem. The profile is defined so that nodes in which remote control of the modem, and hence adaptive data rate, is not available will interoperate with nodes which do have the capability. david a koch theater
