| Abstract(in English) | This paper introduces a frequency compensation method applicable to multiple access in Direct Spectrum Division Transmission (DSDT). In the transmitter (Tx) side, DSDT divides the single carrier modulated signal into multiple sub-spectra and assigns them to unused frequency resources. In the receiver (Rx) side, the divided sub-spectra are combined and the single carrier modulated signal is regenerated. To realize multiple access in DSDT, we propose a frequency compensation method that changes the filter coefficients of the combining filter sequentially based on the estimated frequency compensation value, and establishes frequency synchronization after the spectrum combination filter bank. Experiments show that it holds the C/N degradation to less than 0.7dB, regardless of the spectrum division number. |
