Many studies have been undertaken in the recent past to create a Multiple Input Multiple Output (MIMO) system to provide higher-quality multimedia services at a larger data rate. It can handle high-speed applications without the need for additional communication resources like power or bandwidth. In order to meet these objectives, this work proposes a novel multi-dimensional Quasi Orthogonal Space Time Block Code (QOSTBC) scheme based on code word diversity. The phrase "code word variety" was coined because the information symbols were spread across multiple code words, in addition to typical time and spatial dispersion, without requiring more transmission power or bandwidth. Because code words give more diversity, a receiver with complete channel state information can estimate transmitted symbols with a lower risk of error. The simulation data revealed a considerable improvement in the suggested scheme's Bit Error Rate (BER) performance when compared to conventional schemes.
