But, if you encode N states (log2(N) bits) onto each symbol, each bit effectively gets only a portion of the energy of the symbol. On the other hand, the noise energy of each bit in a symbol does not divide. This is the key point to grasp. hillbillies truck stop

What Is PAM4? Understanding NRZ and PAM4 Signaling

WebThe symbol for the binary digit is either "bit" as per the IEC 80000-13 :2008 standard, or the lowercase character "b", as per the IEEE 1541-2002 standard. Use of the latter may create confusion with the capital "B" which is used for the byte. History [ edit] WebThe bits per symbol is the (modulation's power of 2) × (Forward Error Correction). So for example, in 64-QAM modulation 64 = 2 6 so the bits per symbol is 6. The Forward Error Correction (FEC) is usually expressed as a fraction; i.e., 1/2, 3/4, etc.
