Concatenated Convolutional Coding ( CCC) is key technology in channel coding, which can provide near Shannon bound performance. 级联卷积编码是目前信道编码领域研究的热点,它能够提供接近Shannon极限的性能;
All the feature values are concatenated to form a feature vector. Both templates are used in later research on biometric cryptosystem. Secondly, this paper proposed a key generation algorithm based on binary code of palmprint feature. 这两种形式的特征模板分别被用于后续的生物加解密系统的研究中。本文提出了一种基于二值码掌纹特征的密钥生成算法。
