Abstract:

In 5G mobile systems, Non-Orthogonal Light Acquisition (NOMA) and Multiple End-to-End (MIMO) technologies must overcome numerous obstacles, including space limitations, connectivity restrictions, and the requirement for increased reliability. It is vital to concentrate on enhancing and reconsidering criteria of BER, SE, average power rate and potential for a link transmission error in order to boost performance in 5G networks using MIMO. Phase modulation was accomplished in a few frequency channels by the suggested model, which took into account input power, bandwidth, transmission power, and signal-to-noise ratio. Following an evaluation of the model's efficacy, the results showed superior performance over earlier research. The transmission findings demonstrate that MIMO-NOMA enhances the critical user's bit error rate and transmission power. The average active rate was used to determine link transmission outcomes. Furthermore, in both uplink and downlink scenarios, with and without MIMO, NOMA's BER, SE, average power rate & failure probability was assessed. Study discovered that MIMO-NOMA installation significantly improved performance for all users.
