The optimum ratio between the rings with 16APSK modulation for transmission over an AWGN channel is the one giving the same Euclidean distance between the points on the inner ring and between the two rings:
26 and 27, simulation results of the BER with 16APM and 16APSK are shown for different signal-to-noise rations and rig factors.

Shiron proved its technology leadership again by being the first to demonstrate live a two-way IP broadband VSAT system transmitting DVB-S2 16APSK modulation, saturating a full transponder on the outbound and receiving 8PSK modulation on the inbound," said Oscar Glottmann, Shiron's VP of Sales and Marketing.
By utilizing 16APSK modulation and a high forward error correction code rate on our DVB-S2 outbound signal, we achieved a world record in satellite space segment spectral efficiency, transmitting 117 Mbps over a 36 MHz transponder, with over three bps/Hz on the outbound," explained Dr.
For the other cases, including, for example, professional/interactive applications and advanced broadcasting using 16APSK and 32APSK, the program will be administered by each entity (contacts: DIRECTV: John T.
