摘要
En 中文
A new construction combining LDPC convolutional codes and multilevel coding/modulation is suggested and analyzed. In the case of QPSK, we demonstrate that it has a better performance than an LDPC convolutional code combined with conventional Gray mapping. (c) 2004 Elsevier GmbH. All rights reserved.
