Today Massive multiple-input multiple-output is a promising technology because of the savings in both spectrum and energy costs that may be achieved by relatively simple signal processing. Recently, however, it has been shown that using code domains NOMA in mMIMO may enhance the SE performance in an overloaded situation where the number of UEs is greater than the number of antennas, leading to a worse error rate performance. Interleaved divisional multiple access (IDMA) has also received considerable interest as a potential NOMA (non-orthogonal multiple access) standard for the coding domain. This research makes two distinct proposals: first, an exceed the permissible inputs and generates a report (MIMO) and IDMA network infrastructure is jointly offered, in which transmitters on the base station serve users concurrently in the same frequency range. The numbers of both and are rather huge. Second, for a large MIMO-IDMA system with downstream communication restraints, it is proposed to use a beamformer based on the minimal mean square error (MMSE) to battle propagation loss and the influence of multiple access interfering (MAI). Performance of the suggested system using MMSE beamforming has been analysed by plotting the bit error rate (BER) against the signal-to-noise ratio (SNR), based on simulation results.
