The integration of multiple input multiple output (MIMO) -orthogonal frequency division multiplexing (OFDM) has massively received attention due to its reliability, spatial multiplexing gain and improved spatial diversity gain. However, the MIMO-OFDM is affected because of the errors that occurred during the communication such as inter symbol interference, and inter carrier interference (ICI). In this research, the error correction using hybrid coding algorithm (EC-HCA) is proposed for correcting the errors that occurred during the data transmission. The combination of quasi cyclic low-density parity check (QC-LDPC) and space time block coding (STBC) approaches are used in the hybrid coding which helps to achieve better data broadcasting over the MIMO-OFDM. Here, the interference among the transmitting antennas is avoided by using the STBC. Therefore, the ICI and inter symbol interference (ISI) that occurred in the MIMO-OFDM is minimized by the EC-HCA and it leads to achieving less BER. The performance of the EC-HCA method is analyzed by means of the bit error rate (BER) and peak signal to noise ratio (PSNR). The existing researches such as AED, PC-CC and TC-OPA are used to evaluate the performance of the EC-HCA method. The PSNR of the EC-HCA for 2 × 2 MIMO-OFDM is 10.24 dB which is high when compared to the AED, PC-CC and TC-OPA.

“…A PAPR reduction technique in a MIMO-OFDM system has recently been proposed in [22] wherein, a hybrid approach combining turbo coding and enhanced switching differential algorithm-based partial transmit sequence is considered to accomplish PAPR as well as BER reduction. The authors of [22] also propose another approach in [23] for massive MIMO-OFDM systems by incorporating a distributive population-based switching differential evolution strategy in the selected matching technique that also achieves significant PAPR reduction. In both the cases, the specific methodology to accomplish reduction in PAPR (and BER) is however, considerably different as compared to what we are accomplishing in this study.…”

The ever-increasing end user demands are instigating the development of innovative methods targeting not only data rate enhancement but additionally better service quality in each subsequent wireless communication standard. This quest to achieve higher data rates has compelled the next generation communication technologies to use multicarrier systems e.g. orthogonal frequency division multiplexing (OFDM), while also relying on the multiple-input multiple-output (MIMO) technology. This paper is focused on implementing a MIMO-OFDM system and on using various techniques to optimize it in terms of the bit-error rate performance. The test case considered is a system implementation constituting the enabling technologies for 4G and beyond communication systems. The bit-error rate optimizations considered are based on preceding the OFDM modulation step by Discrete Fourier Transform (DFT) while also considering various subcarrier mapping schemes. MATLAB-based simulation of a 2 ? 2 MIMO-OFDM system exhibits a maximum of 2 to 5 orders of magnitude reduction in bit-error rate due to DFT-precoding and subcarrier mapping respectively at high signal-to-noise ratio values in various environments. A 2-3dBs reduction in peak-to-average power ratio due to DFT-precoding in different environments is also exhibited in the various simulations.

To achieve the ever rising demand for high data rates with high spectral efficiency, the energy efficient massive Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) will be essential and useful for future wireless communication systems as well as Industrial network applications to reduce the operational costs significantly. But the high Peak to Average Power Ratio (PAPR) in a massive MIMO-OFDM system is identified as a critical issue that causes the non-linear signal distortion and restricts the efficiency of the power amplifier. Among different PAPR reduction schemes, Selected Mapping (SLM) is a distortionless technique and highly attractive due to its simple implementation capability. However, the conventional SLM scheme is inefficient for the massive MIMO-OFDM antenna system for its enormous Side Information (SI) burden and large computational complexity to search the best set of phase factors. In this paper, a Distributive Population based Switching Differential Evolution strategy is incorporated in the SLM scheme which eventually enhances the searching ability. The algorithm is employed in different antenna grouping (homogeneous and heterogeneous) based massive MIMO systems. The antenna grouping concept in the massive MIMO system minimizes the SI burden. The proposed algorithm for SLM techniques outperforms the existing techniques in terms of PAPR, Bit Error Rate, SI burden, energy efficiency and computational complexity.
