时空调制通信定位综合化系统研究

To meet the challenge of future mobile communication and integrated communication and radiolocation systems, a new space-time modulation technology with multiple antennas is proposed. With the modulation , an integrated system is designed ,which can find direction, carry with messages similar to PSK/OPSK spread-spectrum systems. This project presents how to modulate signal, how to code signal space, how to recover synchronizer carrier frequency, how to demodulate coherently message and estimate azimuth to mitigate multi-path. The performance of bit error rate and accuracy of direction-finding are investigated. Simulation results show that the integrated system is very successful.
