在本文中，我们考虑了Turbo码和多进制正交调制的级联。介绍了一种改进的译码算法，该算法利用了由Hadamard矩阵得到的正交符号的相关性和Turbo码的软输入/软输出模块。这种改进的译码算法可以显著降低误码率，降低误码率所需的信噪比。
In this paper, we consider the concatenation of turbo codes and M-ary orthogonal modulation. A modified decoding algorithm that utilizes the correlated nature of an orthogonal symbol drawn from a Hadamard matrix and the soft-input/soft-output module of turbo codes is introduced. This improved decoding algorithm can significantly lower the error shoulder and reduce the SNR required for a given error probability.
