WebJun 1, 2016 · A gray code is a method of assigning bits to symbols in a manner that adjacent symbols differ in only one bit. For example, symbols in a $4$-PAM constellation can be assigned bits 00, 01, 11 and 10 (as opposed to 00,01,10 and 11) such that all symbols have neighbours with only one bit difference. 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.
