Hi Everyone!

I have a question about Lab 2. When it asks for the symbol error, what does it mean? I think that for 16-QAPSK, each “symbol” represents 2 bits so the bit error may be different from the symbol error. But for QPSK, the symbol error would be equal to the bit error since every symbol is one bit.

But there is another way to think about it where we can consider the output of the r and s matched filters as one symbol. So if you send one bit and erroneously get a 0 on the r matched filter but get a correct value for the s matched filter, the symbol error would be 100% but the bit error would be 50%. Any thoughts?

Thanks! Hassan
