Non-Binary Polar Coded System for the Two-User Multiple-Access Channel
share
This paper presents non-binary polar codes for the two-user multiple-access channel (MAC). The bit error rate (BER) performances of the non-binary polar codes with different kernel factors have been investigated in detail to select a proper parameter from GF(q) for the generator matrix. Furthermore, the successive cancellation decoding for the non-binary polar codes in the two-user MAC is introduced in detail. Simulation results show that the choice of the kernel factors has a significant impact on the block error rate (BLER) performance; moreover, the non-binary polar codes provide a better BLER performance than their binary counterpart in the two-user MAC.
