| Abstract: | In this paper, a new noncoherent coded modulation system based on serial concatenated convolutional codes and independent overlapped observations noncoherent maximum-likelihood sequence estimator is studied. Performance curve of several parameters are given. Simulation results show that this algorithm adds little complexity and achieves the performance closing to coherent coded modulation. |
