摘要
通过把Turbo码当作一种串行级联码进行处理,在改进编码框图和降低奇偶校验矩阵后,得到了一种改进的Turbo码.采用和积算法译码进行仿真,结果显示,该方法降低了译码的复杂度.
Turbo Codes are studied as serially concatenated cedes in this paper. To change the structure of the turbo coder and decrease the density of the parity-check matrices of the codes, a novel turbo code is obtained. The simulation of these cqdes using sum-product algorithm show that the complexity of encoding is decreased.
