Calculate symbol rate for QAM modulation
  1. How do you calculate QAM symbol rate?
  2. What is 16-QAM symbol rate?
  3. How many bits per symbol can you send with 128 QAM?

How do you calculate QAM symbol rate?

The bits per symbol is the (modulation's power of 2) × (Forward Error Correction). So for example, in 64-QAM modulation 64 = 26 so the bits per symbol is 6.

What is 16-QAM symbol rate?

The maximum data rate supported by 16-QAM is 11.5 Mbps.

Thus, a high data rate with up to 4 bits per symbol modulation can be achieved. The number of bits supported by M-ary QAM is given by the following Equation.

How many bits per symbol can you send with 128 QAM?

Description of 128-SP-QAM

This means that 128-SP-QAM carries 7 bits per symbol compared to the 8 bits per symbol of PM-16QAM and that the minimum Euclidian distance between the constellation points is increased by √2 compared to PM-16QAM.
