摘要：
In the present work, we propose to modify and improve (MIMO-FFT COFDM) by (MIMO-MWDT COFDM) to reduce the interference level and increase the spectral efficiency and the complexity of the system. Combining space division multiplexing with multi-wavelet and error correction coding and diversity of Orthogonal Frequency Division Coding (COFDM) for the purpose of improving the performance of wireless systems requires mastery of all techniques. This system (MWDT-COFDM) is new and has many applications in telecommunication systems. In the rest of this paper, we present the MIMO FFT COFDM system block diagram and the MIMO DMWT COFDM system block diagram. Compared with the MIMO FFT COFDM system, the BER of the system can be reduced by more than 10dB. © 2024 Begell House Inc.. All rights reserved.
