Classification: CPC H | IPC H

Claim 0:
1. An electronic device configured to decode quantized signals, the device comprising:
a decoder, wherein the decoder is configured to:
receive a first quantized collection of bits, wherein the first quantized collection of bits is based on data acquired by a first data source, and wherein the first quantized collection of bits represents a compressed first file;
select a first codeword from a first codebook based on the first received quantized collection of bits; and
reconstruct the data acquired by the first data source using the selected first codeword and the received first quantized collection of bits;
receive a second quantized collection of bits, wherein the second quantized collection of bits is based on data acquired by a second data source, wherein the first data source and second data source acquire data independently from one another, wherein the second quantized collection of bits represents a compressed second file, wherein an amount of compression of the compressed second file is greater than an amount of compression of the compressed first file, and wherein the data acquired by the first data source and the data acquired by the second data source are statistically correlated with respect to one another;
select a codeword from a second codebook based on the second received quantized collection of bits and the first received quantized collection of bits, wherein the second codebook is based on the first codebook and a relationship between the first quantized collection of bits and the second quantized collection of bits; and
reconstruct the data acquired by the second data source based on the received second quantized collection of bits and the selected second codeword.
