## 7 Conclusions  
The coming 5G systems need a reliable and safe mobile communication link with a specific large capacity using much easier and cheaper methods. Since the LDCS meet the information-theoretic optimality property and the selection for the transmitting antennae offers the additional order for the diversity, so the LDC-TAS system is introduced in the paper firstly. Contrasted to a multiple antenna-fading channel, the LDC-TAS system is a simple and cheap way to achieve the diversity advantage, and to maintain the high rate for transmission. Authors educed the specific criteria for the antenna selection when the ZF receiver was utilized as well as investigated it by the computer numerical simulations. Finally, the computing simulation results show that this specific max-min-post-SNR criterion, which is specially produced for the ZF receiver, outperforms some other criteria [19; 20]. Moreover, LDC-TAS has the more significant diversity advantage than BLAST-TAS under the same spectral efficiency and is better than STBC-TAS inside the low SNR environment as well.

Once the M antennae are selected through the max-min-post-SNR criterion for the selection, a novel linear antenna synthesis for these linear dispersion codes on the basis of an innovative HYBRID genetic algorithm has been presented and evaluated. The restricted side-lobes class, the width of the main-lobe, as well as the shaped specific beam pattern are contemporarily concerned via maximizing a pretty suitable cost function through the innovative advanced genetic-algorithm-based algorithm. The algorithm presented in the article is able to offer flexibility and a simple insertion of the a priori knowledge under small computing pressure. Furthermore, it is very important that some extensions of the presented approach, which do not have an obvious increase in the algorithm complexity, could still be true.
