Hello
I am trying to see the performance of Viterbi decoder on different bit length data for certain range of Eb/No value(0 to 10 dB). I generate 1000 bits length data, encode it, pass it over AWGN, decode it and simulate the BER. I divide the same original 1000 bits length data into 2 (five hundred five hundred each) and did the same procedure. The same way, divide the original data into 4(2 hundred fifty each) and apply the same procedure. I have seen irregular behavior on the performance despite the fact I sent them the same continuous time channel which is AWGN:-? The curves cross each other and makes it difficult to conclude. Any idea what might cause it?
Hoping to hear your response!
