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.

“…In transmit diversity, the transmitter is equipped with multiple antennas at the transmitter to introduce diversity by transmitting redundant versions of the same signal. The Alamouti technique is a popular algorithm among the transmit diversity techniques [ 138 ]. There are various versions of transmit diversity, such as space-time block coding (STBC) and space-frequency block coding (SFBC).…”

Unmanned aerial vehicle (UAV) antenna tracking system is an electromechanical component designed to track and steer the signal beams from the ground control station (GCS) to the airborne platform for optimum signal alignment. In a tracking system, an antenna continuously tracks a moving target and records their position. A UAV tracking antenna system is susceptible to signal loss if omnidirectional antenna is deployed as the preferred design. Therefore, to achieve longer UAV distance communication, there is a need for directional high gain antenna. From design principle, directional antennas are known to focus their signal energy in a particular direction viewed from their radiation pattern which is concentrated in a particular azimuth direction. Unfortunately, a directional antenna is limited by angle, thus, it must always be directed to the target. The other limitation of a UAV mechanical beam steering system is that the system is expensive to maintain and with low reliability. To solve this problem, we are proposing the use of MIMO technology as a readily available technology for UAV beyond line of sight technology. Although UAV antenna tracking is domiciled in the mechanical beam steering arrangement, this study shows that this native technology could be usurped by MIMO beam forming.
