  The fundamental limits of communication over multiple-input multiple-output
(MIMO) networks are considered when a limited number of one-bit analog to
digital converters (ADC) are used at the receiver terminals. Prior works have
mainly focused on point-to-point communications, where receiver architectures
consisting of a concatenation of an analog processing module, a limited number
of one-bit ADCs with non-adaptive thresholds, and a digital processing module
are considered. In this work, a new receiver architecture is proposed which
utilizes adaptive threshold one-bit ADCs - where the ADC thresholds at each
channel-use are dependent on the channel outputs in the previous channel-uses -
to mitigate the quantization rate-loss. Coding schemes are proposed for
communication over the point-to-point and broadcast channels, and achievable
rate regions are derived. In the high SNR regime, it is shown that using the
proposed architectures and coding schemes leads to the largest achievable rate
regions among all receiver architectures with the same number of one-bit ADCs.
