Currently, communication system plays an important role in people’s lives especially in activities such as mobile communications and internet access. However, the transmission of information via communication channel has a major problem; it is very sensitive to disruptions such as noises, distortions, interferences, and multipath fading. Therefore, the transmitted information is prone to errors or face incorrect detection at the receiver, thus decreasing the system’s performance. One of the techniques to overcome this problem is by applying the channel coding. In this research, a new channel coding scheme based-on multiplication by alphabet-9 is proposed. The proposed coding and encoderdecoder structure are designed by using mathematical derivations. The proposed channel coding scheme is then simulated in a communication system model to analyze its performance in terms of bit error rate (BER) and throughput. The results show that the BER of the proposed channel coding is lower than those of Hamming code and Reed-Solomon codes for a short code-length. Moreover, the throughput of the proposed coding is also higher than those of the Hamming and Reed-Solomon codes. Finally, it can be concluded that the proposed channel coding scheme has an ability to improve the communication system performance. Thus, its application in a digital communication system seems to be very promisingDownloads
