Adaptive transmission construction based on polar codes

Abstract In actual communication scenarios, wireless transmission channels have the nature of heterogeneity. order to ensure that data can be transmitted with high reliability and low delay, this paper designs a quasi-optimal polar code adapt various channel environments, which called Q-polar code. Based on polarization theory codes state information (CSI), index set is designed constructed perform tasks. The simulation results show bit error rate (BER) performance proposed scheme improved compared traditional code, especially when length N small large.
