UDC User Designation Code

Based on the factor graph representation of maximum a posteriori probabilities decoding of the user s information bits and the sum product algorithm, an iterative multiuser decoding based on parallel partial interference cancellation detection for coded CDMA system was proposed.

基于用户信息比特最大后验概率解码的因子图表示及和 -积算法 ,通过干扰估计值的渐进性能分析 ,提出了一种基于并行部分干扰对消检测的迭代多用户解码器 。
