摘要
The influence of the degree profile on the performance of an irregular turbo code (TC) is analysed using hierarchical EXtrinsic Information Transfer (EXIT) charts. Then, an irregular TC concatenated with a post-encoder of unity rate at its output is proposed to improve the distance properties. Through the example of 3GPP2 interleaving, the gain at low but also at high signal-to-noise ratios is illustrated.
