- W2071506211 abstract "To support providing broadband wireless communication services against limited and expensive frequency bandwidth issues, we have to develop a bandwidth efficient system. Therefore, this paper proposes a closed-loop MIMO (Multiple-Input-Multiple-Output) system using pre-coding matrices to optimize capacity and to increase system performance. The grand scenario of this concept is the attained advantages of the pre-coding matrices, which is guaranteed by its derived analysis. First, transformation matrix can allocate transmitted signals power suit to the channel. Second, it can be manipulated in order to maximize the minimum-distance at the receiver. Finally, this pre-coding matrix can mitigate inter-channel correlation. Furthermore, computer simulations validates that our system at 0 dB SNR (Signal to Noise Ratio) can reach optimal capacity up to 1 bps/Hz and error rate up to 0, 1 higher than opened-loop MIMO." @default.
