1. An adaptive sample quantization system comprising: an antenna configured to receive a radio frequency (RF) signal having data encoded therein; analog antenna electronics configured to convert the RF signal to an analog electrical signal; an analog-to-digital converter (ADC) directly coupled to the analog antenna electronics and configured to generate a plurality of consecutive digital samples of the analog electrical signal; and a quantizer configured to determine a mode based on the plurality of consecutive digital samples and to select at least one threshold based on the determined mode, the quantizer being further configured to compare each digital sample with the at least one threshold to generate a corresponding one of a plurality of output samples having a reduced number of bits relative to the respective digital sample to substantially mitigate potential interference and to facilitate extraction of the data.
