Theoretical Analysis of Bit Error Probability for 4-State Convolutional Code with Max-Log MAP Decoding

Abstract

In this letter, a theoretical analysis of bit error probability for 4-state convolutional code with Max-Log-maximum a posteriori probability (MAP) decoding is presented. This technique employs an iterative calculation of probability density function of the state metric per one transition, and gives the exact bit error probability for all signal-to-noise power ratio.
