چکیده

Fast tracking and security are important factor for data transmission in wireless communication. Retrodirective antenna(RDA) is possible for the high-speed beam tracking without any priori location information. Therefore, RDA system is appropriate technology in wireless mobile communication. Also, it is possible to improve security by making direction toward the source. In this paper, we propose the security communication system based on digital RDA. Simulation results show phase conjugation scheme has better BER performance about 1dB and 3dB at source without signal processing than that of without phase conjugation, when phase delay is 15°and 30°.

Ongoing Retrodirective Array Research at UCLA

I. Introduction When receiving a signal from an unspecified direction, retrodirective arrays [1] are able to transmit a signal response to that same direction without any previous knowledge of the source direction. This function is performed automatically, without the use of phase-shifters or digital circuitry. The capability to perform high gain antenna pointing automatically, makes the retrod...

Digital wireless sensor server using an adaptive smart-antenna/retrodirective array

A wireless sensor server is developed based on a reconfigurable active smart-antenna/retrodirective array. The system can serve as both a retrodirective array transponder and a smart-antenna receiver simply by changing the frequency of the local oscillator applied to the mixers, enabling it to best utilize its hardware to suit its communication environment. When operating as a direct-conversion...

Active Phase Conjugation with Multiple Antenna Array Element

In this paper we analyze the temporal and spatial compression characteristics of retrodirective antenna systems wherein active phase conjugation (APC) is deployed. It is shown that under the active phase conjugation Hermitian channel matrix properties result and these lead to opportunities for both temporal and spatial signal compression. The effects of additive channel noise, as well as compre...
