BER performance for downlink NOMA

Abstract EN

Non-Orthogonal Multiple Access (NOMA) is a possible multiple access option for the coming generation of wireless communications that has a higher SE and takes advantage of network resource reuse.

As a result, academic and industry researchers have recently looked into the error performance and capacity of NOMA schemes.

Because of the non-orthogonal nature of NOMA technique, the main disadvantage is users' interference, which is normally mitigated using using interference cancellation techniques such Successive Interference Cancellation (SIC) at the receivers.

In this paper, we investigate the performance of NOMA and the power allocation strategy utilized on BER.

We used BASK modulation with Rayleigh fading channel and AWGN channel.

The numerical results show that NOMA works well in equal and different distances between users.
