Prevalent communication technology demands large volumes of data usage. It is important to have communication systems with good reliability and error-free. The bit error rate is one of the most powerful tool to measure reliable throughput at the end-user. The selection of antennas and the corresponding RF chains also plays the most significant role to the context. Many conventional beams spaces non-orthogonal multiple access (NOMA) techniques are available. However, favorable communication is one of the major problem, and this is due to unfavorable power allocation at Far sector users and Edge sector users along with near sector users. In this paper, we introduced the sector multi-beam space optimal bit error rate NOMA (SMBS-OBER-NOMA) which further reduces the errors due to Intra-/Inter-successive Interference Cancellation and also, further power errors due to power allocation are addressed. Simulation results show that the proposed method reduces optimal bit error rates and complexity.
