QAM Reference Information

J.83 Annex A: Table of constellation, bandwidth, symbol rate and bit rate. 

Channel Bandwidth = 1.15 * Symbol Rate Symbol Rate = Output Bit Rate/m
m = 2, 4, 5, 6, 7, 8 Corresponding: QPSK, 16QAM, 32QAM, 64QAM, 128QAM and 256QAM

8MHz Maximum Output Bit Rate

Maximum Valid Bit Rate = Output Bit Rate * 188 / 204
