Citation Context ...y each symbol is given by b = log2 M.1 We focus on square M-QAM modulation, i.e., b C {2, 4, 6, . }, since there are exact expressions for the symbol error probability of square M-QAM modulation (see =-=[9]-=-). We can easily generalize our analysis to include odd values of b by using an approximate expression for the symbol error probability. Let us for now focus on a specific user and drop the subscript ... |

Citation Context ...M-QAM MODULATION In this section, we extend our analysis to trellis-coded modulation (TCM). Let G represent the effective coding gain achieved by TCM as compared to the equivalent uncoded system (see =-=[12]-=-). In general, the coding gain is a function of both the operating SIR and the modulation level. Hence, the efficiency function for TCM is given by fb (a) - (1 obQ( Q WYGbY))) 2 , (22) where b is the ... |
