This article describes an approach to the design of the decoder, which is designed specifically for implementation on FPGAs. FFT-BP mixed domain decoding algorithm is used that does not exclude the multiplier blocks. Presented in part parallel to the extension of the mixed domain decoder that works for structured codes. Next, carefully analyzed the impact on the final precision of decoding performance. Through modeling and synthesis of the results shown to be advantageous to segment the data stream at the decoder portion 3 with different accuracy. The results also contribute to the accuracy of choice for maximum performance or for some compromise performance complexity.
