摘要

We demonstrate a highly-scalable distributed antenna system enabled by real-time bit-interleaved sigma-delta-over-fiber links. By (time-)interleaving multiple sigma-delta modulated in-phase and quadrature pairs into one bitstream for each fiber, the optical bit-rate efficiency is improved while the remote radio unit complexity remains sufficiently low.
