Sammanfattning

A new construction combining low-density parity-check (LDPC) convolutional codes with multilevel coding/modulation is suggested and analyzed. For the case of QPSK and transmission over the additive white Gaussian noise (AWGN) channel, it is demonstrated that it performs better than an LDPC convolutional code with conventional Gray mapping.
