Abstract: One example includes an ACM transceiver system. An ACM transceiver system includes an ACM controller configured to receive a reported signal-to-noise ratio (SNR) via each of a plurality of return signals corresponding to a respective plurality of transmit signals that were each sequentially previously transmitted from the ACM transceiver system in a respective modulation and coding scheme (MODCOD).

The dual-polarization transmissions support both dual transmission and dual diversity configurations. The adaptive receiver techniques include adaptive channel matched filtering and adaptive equalizing at the modulation-symbol rate.
