WitrynaSpecifically, three cases are investigated: 1) both the transmitter and receiver have imperfect CSI; 2) perfect CSI is available at the receiver but the transmitter has no CSI; 3) perfect CSI is available at the receiver but the channel estimation error at the transmitter is norm-bounded. WitrynaThe simulation results verify that our two proposed schemes can alleviate the effect of imperfect SIC and outperform two conventional power allocation schemes which maximize the sum rate and the energy efficiency without considering imperfect SIC. In addition, our proposed schemes achieve near-optimal performance with very low …
Witrynawith imperfect successive interference cancellation (SIC). For example, the authors of [21] derived closed-form expressions for the union bound on the BER of downlink NOMA with imperfect SIC over Nakagami-mfading channels. Although the derived bounds are useful to estimate the BER, the results presented in [21] show that the bounds may … WitrynaBased on the transformation, we propose an iterative power allocation algorithm. Then, we consider the SIC error and the power order constraints in the optimization problem …

Witrynathe angular domain. Relaxing the assumption of perfect SIC at receivers as in [10], [17], [18], we investigate the more practical NOMA scheme with imperfect SIC. To measure the channel correlation between the selected user pair and the EVEs from a stochastic geometric framework, we derive the probability mass function (PMF) of the number of …
