Bit Error Rate For Qpsk Matlab Code

Thought that SER & BER are the same ber of qam but did my research to find that BER is $\dfrac{1}{\log_2(M)}$ of SER...(could you please confirm this?) Also found SER for: 4QAM to be: $\text{erfc}\sqrt{\dfrac{E_b}{2N_0}}$ and that of 16QAM to be: $\dfrac{3}{2} \text{erfc}\sqrt{\dfrac{E_b}{10N_0}}$ Are these values correct? Still have problems to find SER for 32QAM... Hope you can help. derivation share|improve this question edited May 13 '14 at 19:26 jojek♦ 6,71041444 asked May 13 '14 at 19:14 John Smith 112 Take a look at this question and its answers: dsp.stackexchange.com/questions/15996/… –Matt L. May 13 '14 at 19:15 still can't understand the relation (not mentioned anywhere in those questions & answers). Also 16QAM & 32QAM weren't covered in that question.. –John Smith May 13 '14 at 19:23 did my research, cant use that formula when dealing with an odd number of bits per symbol, for which bits per symbol for 32QAM is 5... –John Smith May 13 '14 at 19:41 @JohnSmith: The problem is that there isn't a standard definition of what 32-QAM is. For non-square QAM modulations, there are multiple geometries in which you could implement the const
