Abstract: In NOMA 5G technologies, optimal resource allocation executes for maximising the system performances. Resource allocation such as channel estimation and power optimisation is imperative because obtained multipath signals at the receiver are deeply mixed and cannot be distinguished. In this work NOMA-based effective Channel Estimation (CE) algorithm named Elman-Recurrent Neural Network (Elman-RNN) has been presented. At the same time, a novel power allocation algorithm based on multi-objective Emperor Penguin Optimisation (EPO) for channel gain and throughput improvement is suggested. These works are implemented in MATLAB Tool. Here channel performance metrics like BER, outage probability, sum rate, channel gain, throughput, and Signal to Noise Ratio (SNR) are measured. Finally, results are compared with existing methods, from that we must know our work and methods are efficient.
