1. A method, comprising: communicating data in a channel, wherein received symbols for the data correspond to points of a received symbol space respectively, and wherein first and second dimensions of the received symbol space correspond to a real part and an imaginary part of the received symbols respectively; partitioning the received symbol space into a plurality of regions; for each region of the plurality of regions, determining a regression model associated with a bit of a plurality of bits of the received symbols; obtaining a first received symbol for the data; determining a first region of the plurality of regions of the received symbol space for the first received symbol; and estimating a first log-likelihood ratio (LLR) for a first bit of the first received symbol using a first regression model associated with the first region and the first bit of the first received symbol, wherein the first regression model includes a plurality of regressors.
