"WebFor example, for Rate 3/4 QPSK (where modulation order = 2) Symbol rate = bit rate * 0.666. Re-arranging: Bit rate = symbol rate × modulation order × code rate. So, in changing to a higher modulation order or code rate , the bit rate is increased, and in changing to a lower modulation order or code rate, the bit rate is decreased. " - Coding vs modulation
