求翻译：双迭代接收机由三个串行级联块组成，其中r表示采样后的接受数据。Z和z分别表示CPM符号估计和相位修正后的CPM符号。I是已编码比特，d表示数据比特。初始时，由于没有先验信息可用，均衡迭代以没有干扰抵消的MMSE均衡开始。输出端的每一个符号估计被映射到一个由式（）表示的修正后相位的Q，进制CPM符号矢量中。这个矢量作为后端迭代解调和译码器的输入，解调器和译码器都采用基于格型的最大APP译码算法。处于中心的CPM解调器能够产生交织后编码比特IND 软信息？是什么意思？

Double iterates the receiver to be composed by three serial cascade blocks, after in which r expression sampling accepts the data.Z and z expressed separately the CPM mark estimated and the phase revises after the CPM mark.I has coded the bit, d expresses the data bit.When initial, because does not

Dual iterative receiver is made up of three blocks of serial cascaded, where r is the accepted data sampling. Z and z represent CPM CPM symbol after the symbol estimation and phase correction.
