While a digital communication system transferS data, a receiving end may receive error
messages because of non predictable interferences or noises. Therefore, a channel cod ing
is used to effectively reduce the bit error rate, without raising the transmission power, which
typically occupies par tial bandwidth for transmission but ensures that the bit error rate is
controlled in an acceptable range. In recent years, the data transmission is required day by
day. For a future data transmission, the coverage becomes wider and the transmis sion rate …
