Another advantage , contrast to using convolutional codes or turbo codes , is its low complexity while maintain high ber performance because the check equations are used to terminate the both iterations . we develop the theoretical error free feedback bound for bpcm - id and predict the threshold for decder convergence using the extrinsic information ransfer chart ( exit )
利用非正则ldpc具有不同度的信息节点概率密度演化的差异,对高阶星座中具有较高级别的子信道提供额外的保护,可使迭代反馈判决时,星座子集拥有最大的无错反馈欧氏距离调和均值,从而改善系统的迭代收敛特性。
