How do you calculate QPSK symbol rate?

In digital television transmission the symbol rate calculation is: symbol rate in symbols per second = (Data rate in bits per second × 204) / (188 × bits per symbol)

What is symbol transmission rate of QPSK?

Since the symbol rate for QPSK is half of the bit rate, twice the information can be carried in the same amount of channel bandwidth as compared to binary phase shift keying. This is possible because the two signals I and Q are orthogonal to each other and can be transmitted without interfering with each other.

What is the symbol duration of QPSK?

In QPSK, the phase-shift θ(t) assumes one of the four constant values for every two input bits (i.e., the entire duration of a symbol), depending on the two consecutive bits being transmitted.

What is QPSK bit rate?

The rate of change (baud) in this signal determines the signal bandwidth, but the throughput or bit rate for QPSK is twice the baud rate. For example, an ITU-T V. 22 modem uses QPSK to send data at 1200 bits per second over a dial-up phone line.
