Advance Turbo Encoder mechanism for EDAC. The turbo encoder block uses a parallel concatenated coding scheme to encode a binary input signal. Three identical convolution encoders and two internal interleavers are used in this coding scheme shown in figure. An interleaver is used between systematic convolution encoders. Here, we can hit a rate of 1/3, without puncturing and 1/2, with a form of puncturing. The process of puncturing also obtains other code rates
