In recent years, Multiple Input–Multiple Output (MIMO) has been used to expand data transfer for ensuring consistency. The transmitter and receiver use several antennas and they can achieve high spectral characteristics. The numbers of users and antennas increase rapidly questions the stability and reliability of the system. When MIMO is deployed, the complexity of the system increases and it becomes a major problem in many detection systems. When more and more number of receiver and senders pre-require an increased number of hardware components and a part it further increases the system's complexity and design. It is important to develop sophisticated components to improve compliance with many standards without compromising the Bit Error Rate (BER) performance of the components. The proposed work introduces a New Hybrid MIMO Detector (NHMD), which provides the solution for the complicated design procedure. The core concentration of this work is to minimize the complexity (Hardware) of the system by applying simplest design approach. This Hybrid system with a minimalistic detection approach helps in improve the BER: (Bit Error Rate) of the framework without compromising the overall performance of the system. This proposed method is designed on the Modified Optimal Differential Evolution (MODE) algorithm which is used to apt the best detector by deploying the objectives of this work. In addition, this method uses parallel processing to reduce the amount of arithmetic logic. The proposed NHMD method is implemented for cylindrical devices belonging to different FPGA families with different antenna configurations (2 × 2, 4 × 4). The proposed NHMD method provides superior quality by combining multiple detectors. The simulation results confirm that the NHMD method uses low equipment as well as low power consumption and provides high efficiency without affecting BER performance.
