The invention discloses a Turbo code interleaver implementing method, firstly calculating interleave matrix parameters including number of rows, minimum rank, and number of columns of the interleave matrix and the primitive root corresponding to the minimum rank; making interleave matrix row-inside displacement; finally generating interleave address. And it simplifies the steps of interleaver implementation, and advances a blank-row pre-deleting technique and further saves the required storage resources, and it adopts a new row-inside replacement mode and mainly implements main operations in iterative computation or table-look-up mode. In hardware implementation, it avoids all modulus and multiply-divide operations so as to real-time implement interleave/ de-interleave address.
