Method and system for adaptive coding and modulation (ACM) for supporting mesh network connectivity for multipoint networks

A method of communicating between remote terminals within a hub-spoke network, the method comprising:

• receiving, by a hub, information about a plurality of remote terminals indicating communications link requirements of each remote terminal;
• receiving, by a first remote terminal of the plurality of remote terminals, information about a second remote terminal of the plurality of remote terminals from the hub;
• selecting, by the first remote terminal, a modulation factor, coding rate, symbol rate, center frequency, and power level based on the information received about the second remote terminal;
• transmitting, by the first remote terminal, a signal using at least one of the selected modulation factor, coding rate, symbol rate, center frequency, and power level, to the second remote terminal such that a communications link is created;
• and
• adjusting at least one of the symbol rate and center frequency of the transmitted signal such that performance of the link is increased while maintaining a presence of the link;
• wherein signals sent by a hub to the remote terminals are sent through a common outbound channel and signals sent by the remote terminals to the hub are sent through one or more single channel per carrier (SCPC) channels.
