Abstract:

In this letter, a novel maximizing signal-to-interference ratio (max-SIR) time-frequency packing scheme for multicarrier faster-than-Nyquist signaling is proposed. The proposed scheme is based on the low complexity symbol-by-symbol detector. Specifically, we optimize the time-frequency spacing under the given signaling efficiency to maximize the SIR, i.e., the ratio between the energy of useful signal and the intersymbol interference and intercarrier interference introduced by time-frequency packing. We show that the proposed max-SIR time-frequency packing outperforms other time-frequency packing schemes for both the symbol-by-symbol detection and coupled with successive interference cancellation.
