المستخلص: The end – to – end transfer of data from a transmitting application to receiving application involves many steps, each subject to error, with adequate error control, we can be confident that the transmitted and received data are identical. Errors can occur at both the bit and the packet levels. Error control is the process of detecting and correcting both bit and packet errors. In this paper, we show combination codes of error control schemes using forward error correction, while keeping an efficient use of the limited bandwidth. We use a Hamming (7,4) code and (12,8) code, in which three checks bits are combined with four information bits to produce a block of data of length n = 7 for (7,4) code, and in which four checks bits are combined with eight information bits to produce a block of data of length n=12 for (12,8) code. A block of data of length 12 is too short to be appropriate for a practical data communications system, but the mathematics involved in longer blocks would become tedious [1].
