摘要

本文研究了由Reed-Solomon码组成的turbo积编码方案。提出了一种改进的Chase算法，以满足对q元符号的要求，并将其用于迭代q元译码算法的实现。验证了迭代q元译码算法与二进制turbo算法相比具有较低的复杂度。仿真结果表明了该算法的有效性

Um Algoritmo de Decodificação Iterativa q-ária para Códigos Turbo Produto

— This article considers the study of turbo product encoding schemes constructed from components Reed-Solomon codes. A proposal of modiﬁcation of the Chase algorithm is developed to satisfy q -ary symbols requirements and is used in the implementation of a iterative q -ary decoding algorithm. It is veriﬁed that the iterative q -ary decoding algorithm presents a reduction of complexity when compared to the binary turbo algorithm. Simulation results are presented to show the effectiveness of the proposed algorithm
