How do you calculate symbol rate from data rate?
symbol rate in symbols per second = (Data rate in bits per second × 204) / (188 × bits per symbol)
What is the symbol for rate?
A ratio r=a/b has both a numerator "a" and a denominator "b". The value of a and/or b may be a real number or integer. The inverse of a ratio r is 1/r = b/a. A rate may be equivalently expressed as an inverse of its value if the ratio of its units are also inverse.
What is the symbol rate of 256 QAM?
As the number of symbols increases, more data bits are transmitted per symbol. For example, 64-QAM is a QAM scheme with 64 symbols, and 256-QAM is a scheme with 256 symbols. 256-QAM conveys 8 bits per symbol (as 256 = 28), so achieving twice the data rate of 16-QAM for the same symbol rate.
Is Symbol rate the same as bandwidth?
The required bandwidth is related to bit rate and the modulation order M. It is so that the double sided bandwidth w = symbol rate= bit rate rb/ divided by the number of bit per symbol n. The number of bits per symbol is = log 2M with M is the M is the QAM modulation order.
