| 摘要: |
| 针对规则LDPC码，采用了行列都均匀的(evenboth)随机构造H的方式，在瑞利平坦衰落信道下和卷积码的性能进行了对比，证明了规则LDPC码在中短帧传输下在瑞利平坦衰落信道的优异性能。这对LDPC码应用于实际无线通信系统具有重要参考价值。 |

| Abstract: |
| Through row and column even (evenboth) method to randomly produce matrix H, the actual advantages of regular Low Density Parity Check(LDPC) codes under the short and middle frames can be verified through comparing with convolutional codes over the Rayleigh channel. It has refevence value for LDPC codes to be applied in practical wireless communication systems. |
