Center node: "one bit quantizers for fading channels"
  Abstract: We study channel capacity when a one-bit quantizer is employed at the output of the discrete-time average-power- limited Rayleigh-fading channel. We focus on the low signal-to- noise ratio regime, where communication at very low spectral efficiencies takes place, as in Spread Spectrum and Ultra- Wideband communications. We demonstrate that, in this regime, the best one-bit quantizer does not reduce the asymptotic capacity of the coherent channel, but it does reduce that of the noncoherent channel. I. I NTRODUCTION

Connected through hyperedge HE-1 (induced by source paper "at low snr asymmetric quantizers are better"):
  with members:
    - "analysis of 1 bit output noncoherent fading channels in the low snr regime"
    - "increased capacity per unit cost by oversampling"
