摘　　要：Digital mobile fronthaul(MFH)[1–3]using a common public radio interface(CPRI)is less spectrally efficient compared to analog mobile fronthaul.Delta-sigma modulators(DSM)have attracted much interest in solutions to overcome traditional CPRI bottlenecks because they can support fully digital transmitters and are compatible with advanced CMOS technology[4,5].Typically,using a DSM with oversampling to quantize the baseband signal increases transmission capacity and reduces digital-to-analog(DAC)requirements.
