Abstract
A method of processing a signal by non-uniform quantization of log likelihood ratios is disclosed. A method comprising the steps of: receiving a plurality of bits; calculating a log likelihood ratio, known as a LLR, for each bit; providing a LLR value for each bit based on the calculated LLR; quantizing the LLR values into a plurality of quantization bins, each quantization bin having: a width representative of one or more LLR values; and an index value having a bit length; and associating each bit with the index value that corresponds to its LLR value, wherein the width of each quantization bin is non-uniform. This compresses the LLR values in a more efficient manner, requiring lower memory usage and/or lower bandwidth. A chip for a receiver and a communication system comprising one or more receivers are also disclosed.
