A device for encoding turbo codes for use in satellite communications. Input data including termination bits are supplied to a series of interleaver circuits. Coding circuits perform convolution operations on data output from the respective interleavers, thereby obtaining coded data. The encoding process automatically results in terminated coded data. Thus, termination circuits are unnecessary. The determination of substitute positions by the respective interleavers through arithmetic computations makes it unnecessary to provide separate memory to store substitute position information.
