Constant Coding and Modulation (CCM) is one of the three coding and modulation schemes for the forward link implemented in OpenSAND.

With CCM, the MODCOD used to encode the packets is constant during the emulation.

OpenSAND Exploitation

CCM is not the default mode of operation in OpenSAND. However, it can be enabled for each forward link carrier from the OpenSAND Manager.

OpenSAND Software Design

In the OpenSAND core, CCM is implemented as a particular case of VCM, with only one MODCOD selected. Refer to the VCM implementation section for more information.
