Abstract:
1. An apparatus for receiving a signal in a communication system, the apparatus comprising: a log-likelihood ratio (LLR) buffer with a plurality of LLR sub-buffers, for buffering an LLR value generated according to each of a plurality of demapping schemes; an LLR demapper for generating a particular LLR value by demapping an input signal according to a particular demapping scheme among the plurality of demapping schemes; an LLR buffer write controller for performing a control operation of buffering the particular LLR value in a particular LLR sub-buffer for buffering an LLR value generated according to the particular demapping scheme among the plurality of LLR sub-buffers; and an LLR buffer read controller for performing a control operation of reading an LLR value buffered in the LLR buffer.
