Comparison Study between 1/2 Rate And 2/3 Rate Convolutional Encoder with Viterbi Decoder
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
As the need for bandwidth by bandwidth application became extremely alarming, the need to design a good encoders and decoders for the next generation wireless communications system became very imperative. Convolutional Encoder with Viterbi Decoder has been proved to be vital in this area. This research is on comparison study between 1/2 rate and 2/3 rate convolutional encoder with Viterbi decoder. The result of the research shows that an increase in the coding rate ‘k/n’ brings about a decrease in signal to noise ratio (SNR) gain of both. Also soft decision coding with width of 2 tends to have a better coding gain as compared to soft decision coding with width of 3.
