N-continuous orthogonal frequency division multiplexing is a modulation technique that achieves a lower-sidelobe transmission signal. However, the calculation (precoding) method requires a wide dynamic range arithmetic. This study considered two decompositions of the precoder matrix for a low-end field-programmable gate array (FPGA) without DSP blocks.(More)
The modulation technique of N -continuous orthogonal frequency division multiplexing (OFDM) has lower sidelobes than those of the original OFDM as a result of the continuous connection with higher-order derivatives between the OFDM symbols. Compared with the other sidelobe suppression schemes, for example, cancellation carrier insertion, and windowing, N(More)
Both N-continuous OFDM and N-continuous symbol padding OFDM (NCSP-OFDM) are modulation techniques that achieve a low sidelobe transmission signal. This study compares the timing synchronization performance of these modulation techniques by using a simple non-data-aided algorithm. The experimental results indicate that the timing metric curve of N-continuous(More)
