在本文中，我们提出了一种串行级联涡轮编码快于奈奎斯特信令 (FTNS) 收发器，该收发器考虑了 FTNS 特定的有色噪声效应。所提出的低复杂度接收器借助最小均方误差准则进行软判决频域均衡，同时白化有色噪声。仿真结果表明，所提出的多级级联 FTNS 系统比以前在高符号封装 FTNS 机制中不考虑有色噪声效应的系统实现了更好的误码率性能。此外，作为所提出的迭代解码器的一个显着优点，以实际解码复杂度实现了接近容量的性能。
In this paper, we propose a serially concatenated turbo-encoded faster-than-Nyquist signaling (FTNS) transceiver that takes into account FTNS-specific colored noise effects. The proposed low-complexity receiver carries out soft-decision frequency-domain equalization with the aid of the minimum-mean square error criterion while whitening the colored noise. Simulation results demonstrate that the proposed multi-stage-concatenated FTNS system achieves a better error-ratio performance than previous systems that do not consider colored noise effects in the high-symbol-packing FTNS regime. Furthermore, as an explicit benefit of the proposed iterative decoder, near-capacity performance is achieved with practical decoding complexity.
