Bits to symbols
WebApr 16, 2024 · The set of symbols in a modulation is called the "constellation". 4-QAM's constellation is $(1+j, 1-j, -1+j, -1-j)$, and how you assign specific bit patterns to different symbols can be a design choice, but using "gray code" is common. WebQuestion: Consider a 4-QAM constellation and the following mapping from bits to symbols ño S2 00 S1 O VES 10 → 531 01 S2 + SE + VE LE 11 S4 Sy The probability of symbols Pr(S1) =a?, Pr(53)= Pr(52) = (1-a)a, Pr(54) =(1-a)2 where "a". is a parameter. Consider transmission over AWGN channel with noise power No.

WebNov 6, 2010 · 4 Answers. You would only need 5 bits because you are counting to 26 (if we take only upper or lowercase letters). 5 bits will count up to 31, so you've actually got more space than you need. You can't use 4 because that only counts to 15. If you want both upper and lowercase then 6 bits is your answer - 6 bits will happily count to 63, while ...
