O transmissor de radiofrequência digital (DRF) de 1 bit usando um modulador delta-sigma passa-banda (BP-DSM) pode emitir um sinal de radiofrequência (RF) transportando um fluxo de dados binário com uma taxa de dados constante, independentemente da frequência da portadora, o que torna possível transmitir sinais de RF através de links ópticos digitais com uma taxa de bits constante. Contudo, a ligação óptica requer uma codificação de linha, tal como 8B10B ou 64B66B, para restringir o comprimento de execução e a disparidade, e a codificação de linha corrompe o espectro de potência DRF devido a dados adicionais ou codificados. Este artigo propõe uma nova codificação de linha para BP-DSM, que é capaz de controlar o comprimento de execução e a disparidade do fluxo de dados de 1 bit, adicionando um filtro notch ao BP-DSM que suprime os componentes de baixa frequência. O filtro notch estimula a mudança de dados e equilibra os componentes de corrente contínua (DC). É demonstrado que a codificação de linha proposta encurta o comprimento de execução de 50 bits para menos de 8 bits e reduz a disparidade de vários milhares de bits para 5 bits quando o transmissor DRF de 1 bit emite um sinal LTE com largura de banda de 5 MHz, ao usar frequências portadoras. de 0.5 GHz a 2 GHz e uma variação de potência de saída de 60dB.

Abstract: The 1-bit digital radio frequency (DRF) transmitter using a band-pass delta-sigma modulator (BP-DSM) can output a radio frequency (RF) signal carrying a binary data stream with a constant data rate regardless of the carrier frequency, which makes it possible to transmit RF signals over digital optical links with a constant bit rate. However, the optical link requires a line coding, such as 8B10B or 64B66B, to constrain runlength and disparity, and the line coding corrupts the DRF power spectrum owing to additional or encoded data. This paper proposes a new line coding for BP-DSM, which is able to control the runlength and the disparity of the 1-bit data stream by adding a notch filter to the BP-DSM that suppresses the low frequency components. The notch filter stimulates the data change and balances the direct current (DC) components. It is demonstrated that the proposed line coding shortens the runlength from 50 bits to less than 8 bits and reduces the disparity from several thousand bits to 5 bits when the 1-bit DRF transmitter outputs an LTE signal with 5 MHz bandwidth, when using carrier frequencies from 0.5GHz to 2GHz and an output power variation of 60dB.
