Researchers have shown that practical mobile
communication channels introduce errors that are
concentrated in a certain locality rather than random
errors. These are burst errors caused by deep fading of
the wireless channel or a lightning strike. The existing
Viterbi Algorithm (VA) capable of correcting random
errors is inefficient in correcting burst errors and
therefore resulting in unacceptable amount of residual
errors. This paper presents an assessment of Non-
Transmittable Codewords (NTCs) enhancement
technique to VA in decoding the received signals
subjected to burst errors that may occur in poor channels.
A hard decision, 1/2 rate and constraint length K is equal
to 3 Viterbi Algorithm decoding technique, Binary Phase-
Shift Keying (BPSK) and Additional White Gaussian
Noise (AWGN) are components used in MATLAB
software based simulation when assessing the proposed
technique. Applying 6NTCs to VA decoder enables the
decoder to reduce 83.7 percent of its residual errors.
However, the technique reduces the encoder’s data
transmission rate from 1/2 to 1/6. |
