Objectives: We propose an efficient, scalable, adaptive MIMO-OFDM Technique with IDMA scheme to mitigate the fading issues in underwater wireless communications. Method/Statistical Analysis: MIMO is the technique to transfer the data independently from more than one antenna simultaneously, and at receiver side data is received by one or more than one antenna. This technique increased the data rate while OFDM saves the bandwidth and combat from the fading. IDMA scheme is better than any other available multiple access schemes which show the best performance result in underwater wireless communication. Findings: We test the BER performance of MIMO-OFDM and MIMO-IDMA technique with a different number of users and we found that both techniques show limited performance result. We test the hybrid approach by simulating the MIMO-OFDM with one multiple access scheme i.e., IDMA scheme to reduce the underwater channel noise such as burst error or fading. This technique has the potential to serve as a primer for mitigating the fading issues in future underwater wireless communication. Application/Improvements: MIMO-OFDM with IDMA Scheme is employed to improve the below water communication with the help of the most common device known as hydrophones. Since underwater communication uses acoustic waves instead of electromagnetic waves, therefore, there are low data rates compared to another communication medium. This research is being helpful to reduce the fading issues due to low data rate. In this research, we used the random based interleaver in IDMA scheme. For future improvements, we can use new tree based interleaver in IDMA Scheme. The tree based interleaver is used for generating patterns and user separation.
