LDPC Decoder with an Adaptive Wordwidth Datapath for Energy and BER Co-Optimization
Figure 8
Check node output () distribution using Split-Row Threshold decoder for (2048,1723) LDPC code, which are binned into discrete values set by a 6-bit (1.5 format) quantization. The 3-bit subset can cover all values within the Threshold Region. Data are for dB and , where .
