Abstract
Multiple Input Multiple Output (MIMO) is an advanced communication technology that is often used for secure data transfer for military and other applications while transmitting data with high error and noise. To address this issue, a step-by-step hybrid Quadrature Phase Shift Keying (QPSK) modulation scheme in the MIMO system for a complex Very Large-Scale Integration (VLSI) format is recommended. When compared to Binary Phase Shift Keying (BPSK), this approach provides twice the data rate while using half the bandwidth. The complexity is lowered through multiplication and addition, as well as error and noise reduction in data transport, and MIMO detection is accomplished through the combination of two techniques, Inverse Fast Fourier Transform (IFFT) and Stepwise Exponential Companding (SEC). IFFT converts frequency to the time domain, reducing complexity by 23.56 percent in multiplication and an extra 34.05 percent. Likewise, hierarchical high-speed mixing decreases difficult limits by 13% and the addition problem by 25%. This technological outcome results in a decreased Signal-to-Noise Ratio (SNR) and Bit Error Rate (BER).

Summary
Mobile transmission is an important component of everyone’s daily life in terms of communication. The incoming data is wrecked due to uncorrelation and the existence of noise, the two signals are blended to recover the original data with higher quality [12] The similarity between this technique and others is that greater noisereduced information was obtained by evaluating both identical signals from several communication receivers. The Space-Time Coding (STC) technique is one method for providing diversity at the source side by using numerous antennas [13] Spatial multiplexing is another MIMO technique for improving performance. The number of transmitter and receiver antennas utilized in the spatial multiplexing technique can improve the throughput of any system exponentially [14]. When the presence of scattering is high enough to decode the number of signals received from distinct types of sending antennas, the matrix function of a wireless channel is reversed [16]. The MIMO transceiver can discover an operating point in the region of gain of multiplexing and diversity based on wireless channel characteristics [17]
