提出了一种新型的纠错码──之型码 ,它可形成非常简捷的软输入 /软输出译码规则，而且仿真结果表明，其性能在误比特率为 10－ 5处距香农理论极限仅 0.9dB。
A new type of error correction code is proposed, which can form a very simple soft input / soft output decoding rule. The simulation results show that its performance is far from Shannon’s theory limit at the bit error rate of 10-5 Only 0.9dB.
