抜粋

We propose a novel channel coding scheme for 1-bit digital radio frequency (DRF) transmitter comprising a 1-bit band-pass delta-sigma modulator (BP-DSM). This 1-bit DRF transmitter outputs radio signals generated only by a digital circuit instead of an analog circuit. In addition, the 1-bit DRF transmitter can handle arbitrary modulated waveform as the 1-bit digital pulse train, thereby making it easy to transmit RF signal on a digital optical link whenever using DRF signal as the binary data. However, the optical link usually does not send data, having long run length, and has to use a channel coding such as 8B10B, 64B66B and Manchester coding, which needs additional data and causes DRF power spectrum change. To this end, we proposed a novel channel coding scheme able to control the run length without any additional data while converting the RF signal to a 1 bit digital train. We demonstrated that a new coding scheme shortens the run length from 38 bits to less than 7 bits even if the 1-bit DRF transmitter outputs an LTE signal with 5MHz bandwidth in the carrier frequency from 0.5 GHz to 2 GHz.
