Low-complexity FTN receivers based on frequency domain iterative decision feedback equalization
Faster-than-Nyquist (FTN) signaling can improve the system effectiveness without reducing the system reliability,but the fierce inter-symbol interference (ISI) introduced by it may cause that the complexity of the optimal receiver is intolerable.An effective low-complexity FTN receiver is iterative...

| description | Faster-than-Nyquist (FTN) signaling can improve the system effectiveness without reducing the system reliability,but the fierce inter-symbol interference (ISI) introduced by it may cause that the complexity of the optimal receiver is intolerable.An effective low-complexity FTN receiver is iterative block decision feedback equalizer (IBDFE),which can achieve performance close to the optimal receiver with much lower complexity,but its complexity can be further reduced.Therefore,a reduced-complexity IBDFE (RC-IBDFE) was proposed for FTN communication systems,which was based on IBDFE,but introduced a simplified method to design the feedforward and feedback filters.When packing factor is τ={0.8,0.7},numerical results and analysis indicate that,compared with IBDFE,RC-IBDFE has stronger robustness,its complexity is reduced by {45.7%,25%},and its performance gain is {0.605 4,0.193 6} dB when the bit error rate (BER) is 10<sup>-5</sup>.Compared with the existing low-complexity IBDFE (LC-IBDFE),RC-IBDFE has stronger robustness,its complexity is reduced by {13.6%,-25.8%},and its performance gain is {0.289 7,0.531 2} dB when the BER is 10<sup>-5</sup>. |
