现在的雷达都是在多脉冲观测的基础上进行检
测的,多个脉冲积累后可以有效地提高信噪比,从
而改善雷达的检测能力。积累处理可以在包络检波
前完成,称为检波前积累或者中频积累。信号在中
频积累时要求信号间有严格的相位关系,也就是说
信号是相参的,所以也称为相参积累。此外,积累
过程可以在包络检波后完成,称为检波后积累或者
视频积累。由于信号在包络检波后失去了相位信息
而只保留了幅度信息,所以检波后积累处理就不需
要信号间有严格的相位关系,因此这种积累又称为
非相参积累。实现非相参积累的方法有很多,例如
抽头延迟线积累(FIR 积累)器和反馈积累器。

RSC_BCJR_Mfile_Tail
本程序设计的是咬尾编码的turbo码,用matlab编写。咬尾turbo码也即不需要拖尾比特,使得前后两个状态相同,译码采用修正的MAP译码算法(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, decoding, MAP decoding algorithm using modified)
