Performance Analysis of IRS-aided Short-Packet NOMA Systems over Nakagami-m Fading Channels

“…Also, considering the advantage of IRS, [14] and [15] analyzed the MAR and average BLER of IRS-aided SPC systems over various fading. To the best knowledge of the authors, the performance of IRS-aided short-packet NOMA systems has not been investigated until very recently by [16], where the authors considered random and optimal CPSs.…”

“…We note that there are three limitations in [16]. First, [16] only considered Rayleigh fading, which is not a generalized fading model.…”

“…First, [16] only considered Rayleigh fading, which is not a generalized fading model. Second, [16] did not optimize the blocklength and power allocation coefficients for the considered system. Third, [16] did not touch DPSs at the IRS, which is a more feasible option than CPSs for practical use.…”

“…Second, [16] did not optimize the blocklength and power allocation coefficients for the considered system. Third, [16] did not touch DPSs at the IRS, which is a more feasible option than CPSs for practical use. In order to overcome these limitations, we analyze the BLERs of an IRS-aided short-packet NOMA system over generalized Nakagami-m fading, which encompasses Rayleigh fading as a special case.…”
