dc.description.abstract |
Polar codes are decoded using successive cancellation (SC) algorithm where likelihood
ratios (LRs) for data bits are calculated in a sequential manner, and decisions are made
using the calculated LRs. During the decoding of an information bit, the decision results
for the predecessor bits are used, and a wrongly decided predecessor bit has negative
effect on the accurate calculation of the LR for the information bit being decoded. In SC
algorithm, when LR=1, the information bit is decoded as u ̂_i=0, however, such a
decision has 50% of chance of being correct. In this paper, we propose improved polar
decoders utilizing a number of SC decoders. We consider the case of LR=1, and propose
polar decoder structures for the more accurate calculation of the LRs of the successor
bits |
