I'm currently doing a project Implementing Pragmatic Trellis coded modulation by genetic algorithm based cognitive radio. it involves 5 different types of scenario.
I'm also doing a simulation on the sensitivity analysis of the transmission parameters. I'm encountering a problem when i'm conducting a modulation index sensitivity analysis involving 4 different modulation schemes. (uncoded BPSK, coded 32psk , uncoded 128 QAM, and coded 256 QAM. for example in minimizing bit error rate scenario... the fitness score should be where (highest to lowest) uncoded BPSK, 32 coded psk , uncoded 128QAM and then coded 256 QAM.
BUT my simulation result is giving me (highest to lowest ) coded 256QAM, uncoded 128QAM , coded 32 PSK and then uncoded BPSK.
can someone help rectify the problem i'm encountering. ???
please it's quite urgent.
