10位并行解扰码算法推导(共7页).doc

精选优质文档-倾情为你奉上10位并行解扰码算法推导扰码多项式:输入数据:D0.D9(先D0，最后D9)初始状态:R1.R9=X1.X9,R0=X0 推导过程如下：1.按串行解扰码，第一次打入数据(D0)后: R1=D0 -表示“异或”R2=X1 R3=X2 R4=X3 R5=X4 R6=X5 R7=X6 R8=X7 R9=X8 R0=X9 D0 X52.第二次打入数据(D1)后:R1 =D1R2 =D0R3 =X1R4 =X2R5 =X3R6 =X4R7 =X5R8 =X6R9 =X7R0 =X8 D1 X4r1 =X9 D0 X5r2 =X0r3 =X1r4 =X2r5 =X3r6 =X4r7 =X5r8 =X6r9 =X73.第三次打入数据(D2)后:R1 =D2R2 =D1R3 =D0R4 =X1R5 =X2R6 =X3R
