DESIGNING AN ENCODER STRUCTURE FOR VLSI

Abstract

Polar code is really a new type of error-fixing codes that provably accomplishes the capability from the underlying channels. Because of the funnel achieving property, the polar code is becoming probably the most favorable error-fixing codes. Because of the funnel capacity achieving property, the polar code has become regarded as a significant breakthrough in coding theory, and also the usefulness from the polar code has been investigated in lots of programs, including data storage products. Because the suggested encoder enables high-throughput encoding with small hardware complexity, it may be methodically put on the style of any polar code and also to any degree of parallelism. Because the polar code accomplishes the home asymptotically, however, it ought to be lengthy enough to possess a good error-fixing performance. Even though the previous fully parallel encoder is intuitive and simple to apply, it's not appropriate for lengthy polar codes due to the large hardware complexity needed. Within this brief, we evaluate the encoding process within the point of view of very-large-scale integration implementation and propose a brand new efficient encoder architecture that's sufficient for lengthy polar codes and efficient in alleviating the hardware complexity.
