An optimal positioning of interleaver in digital communication system for error correction technique
Mahindra Umbarkar, Girish Kulkarni · AIP conference proceedings · 2022
At first glance, the Interleaver seems to have an important but limited application. In this article, the two distinct approaches of positioning, that is placement of Interleaver block in Digital communication system is cited. The two approaches are said to be distinct because, the act of Interleaver with same construction will play different role. In combination with FEC code the Interleaver must be placed just after the encoder and for parallel Concatenated code the Interleaver need to be place before the encoder. It is well-known that the interleaver plays a very important role in the performance of channel codes and their construction using random and fixed permissions. The forecasting error correction codes (FEC) followed by the interleaver play a major role in improving the performance of digital system error by combating random and explosive errors. An interleaver is a hardware device that is often used in conjunction with an error correction code to prevent the effect of explosion errors. In this paper, we introduce Interleaver programs in two different ways. A simple Interleaver with the same properties can be used for two different effects to improve communication performance with a different effect.
