Nowadays, the use of digital communication has been highly demanding. The advanced communication is needed by people to communicate with each other at anywhere, anytime and any place. Therefore, the better performance of communication systems is very important. Extraordinary efforts have been done by many scientists to achieve better performances of digital communication. Over than 50 years, the researchers have been working hard to develop the state of the art of digital communication. Due to this phenomenon, this paper try to acquire well performance of trajectory using serial concatenation of coding. Here, two kinds of channel coding are applied, namely: BCH and Convolutional codes. Furthermore, there are also decoding process using BCJR algorithm which is implemented in the inner and outer decoding scheme for both codes. In addition, several impacts of interleaved in the EXIT chart are going to present using three types of different length of interleaver. As a result, using quite long of interleaver length, is going to produce well-match the trajectory plot and also the EXIT chart. Lastly, outer codes is well-shown by applying a BCH code for decoding process, while Convolutional code is quite good for inner codes. © 2013 IEEE.
