3. Is QAM and Pam same?
4. How many bits can 1024 QAM represent?

Is QAM better than QPSK?

The performance of QPSK is superior to QAM. The bit error rate of QAM is high as compared to QPSK.

Which is better QAM or PSK?

The result shows that the performance of 4-QAM is similar to QPSK. Then, 8-QAM is slightly better than 8-PSK, and as the order gets higher, the QAM shows a much better performance than PSK. The constellation diagram of QAM shows that the distance between each combination is constant for any order.

Is QAM and Pam same?

QAM performs much better than the PAM system due to the following reasons: first the noise variance in the PAM system is higher so we expect its error rate to be higher; on the other hand the PAM system is not fully utilizing the bandwidth as opposed to QAM.

How many bits can 1024 QAM represent?

With 1024 QAM modulation, there are more bits per symbol — 10 bits per symbol versus 8 bits in 256 QAM.
