IN ot ei 435 430 11 L ----- (57) : Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing schemes consider punctured bits as unknown bits, and set the log likelihood ratio (LLR) for those bits to zero; while other puncturing schemes con - .::::) N Sider punctured bits as known bits, and set the LLR for those bits to infinity Each of these puncturing schemes has been observed to O provide benefits over the other under different circumstances, especially corresponding to different coding rates or different signal to ,-..f . noise ratio (SNR). According to aspects of the present disclosure, both puncturing schemes are compared, and the puncturing scheme resulting in the better performance is utilized for transmission.
