This implies that the 43rd sample has a
wrong code word. Hence we delayed the time by 5 samples so
that the decoder can sample exactly 43 frames with each frame
having 15 bits or samples. This process is implemented in
Simulink as illustrated in Figure 6. The process of decoding is
used to detect possible errors thereby improving
communication performance by increasing robustness against
channel impairments. The received code word in polynomial
form is given by (10)
