| dc.description.abstract | This project presents the development of a real-time Alamouti Multiple-Input Multiple-Output (MIMO) algorithm across various channel matrix sizes utilizing the WARP Kit Board. The proliferation of wireless communication technologies demands efficient signal processing techniques to enhance spectral efficiency and reliability. MIMO systems have emerged as a promising solution by exploiting spatial diversity to improve communication performance. The Alamouti scheme, known for its simplicity and effectiveness, is implemented in real-time to demonstrate its viability across different channel matrix sizes. The project begins with an in-depth exploration of the theoretical foundation of MIMO systems and the Alamouti algorithm, elucidating their significance in modern wireless communication systems. The WARP Kit Board, with its programmable hardware and software-defined radio capabilities, serves as an ideal platform for prototyping and testing the algorithm. Experimental evaluations are conducted to assess the performance of the developed algorithm across various channel matrix sizes. Through extensive simulations and practical experiments, the impact of channel matrix size variations on system performance, including throughput and bit error rate (BER). The results demonstrate by increasing SNR (dB) leads to lower BER values across all four systems. The 4x4 and 8x8 Alamouti QOSTBC systems show the most significant decreases in BER, nearing zero. The 2x2 Alamouti system achieves a BER reduction of 85.38% to 100%, averaging 96.5%. The 4x4 QOSTBC system reduces BER by 99.66% to 100%, averaging 99.9%. The 8x8 QOSTBC system consistently achieves a 100% BER reduction. | |
