Modified SC Decoding for BDPSK Modulated Polar Codes
Yunxiao Li, Daiming Qu · IEEE Communications Letters · 2022
In this letter, we derive a modified successive cancellation (SC) decoder for binary differential shift keying (BDPSK) modulated polar codes. The proposed decoder takes the phase differences of adjacent even-indexed BDPSK symbols as additional inputs, and the simulations show that the proposed decoder could improve the error performance of polar coded BDPSK systems.
