“…Thus, adverse effects such as BER minimization and inter-modulation interference are caused in the OFDM signal [12 -14]. Therefore, the forward error correction codes are developed for identifying and correcting the errors that occurred in the channel while transmitting the data without any retransmission of the data [15].…”

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.
