I think that $2$ is because the QPSK symbol consists of two bits. But why can the bit error rate be equal to the symbol error rate divided by the number of bits per symbol?

However,the symbol consist of many bits too. e.g.symbol "0" = 000,symbol "7"=111,they all consist of three bits,so what is the difference between frame error rate (FER) and symbol error …

Required to find symbol error rate vs $E_b/N_0$ for 4QAM, 16QAM & 32QAM. Thought that SER & BER are the same but did my research to find that BER is $1/\log_2 (M)$ of SER.

May 3, 2012 · Anyway I am referring to QAM modulation used in US Cable TV. I know it comes under Annex B which is related to FEC. I know that 64 QAM has a symbol rate ~= 5057000 …

The theoretical symbol error rate for 4-QAM is not $Q (\sqrt {2E_b/N_0})$; that's the bit error rate. The $2$-bit 4-QAM symbol can have zero or one or two bit errors ...

Apr 17, 2009 · I want to know is symbol error rate the same as BER?? Symbol error probabilty curve is a graph of what vs what ?? What all data I require to plot a curve of BER vs SNR??

Mar 4, 2017 · The Es_N0 and Eb_N0 are different. Es_N0 is the energy symbol per N0. Eb_n0 is the energy bit per N0. Finally, i used Es_n0, because of the theoretical formula that I found. …

Feb 19, 2022 · In your example, you increase the bit energy by reducing the bit rate while keeping the power constant. In this case, the benefits are exactly equal to those obtained with a rate …

Dec 12, 2017 · For $16$-QAM it is possible to derive an exact expression for the error probabilities $P [E|s_i]$ (and hence for the symbol error probability $P_E$). You can find the …

Dec 8, 2021 · This explains the difference in Symbol Error Rate between QPSK and BPSK (BPSK has a 3 dB better SER), but since QPSK sends 2 bits per symbol we get the same BER.
