Simulation Results

With the development of satellite laser communication, modulation scheme has been the key technique for the modulation subsystem. The performance in terms of bite-error rate of OOK, 2DPSK, QDPSK used in the downlink of the ground-to-satellite laser communication systems are compared with the consideration of the combined effects of both intensity scintillation and detector noise. Simulation results are given and the advantages and disadvantages of the three modulation schemes are also studied. The design of the downlink of ground-to-satellite laser communication system can benefit from this work.

AbstractA novel approach to linear array antennas with adaptive inter-element spacing is presented for the first time. The main idea is based upon electronically displacing the phase center location of the antenna elements, which determine their relative coordinates in the array configuration. This is realized by employing dual-mode microstrip patch antennas as a constitutive element, whose phase center location can be displaced from its physical center by simultaneously exciting two modes. The direction and the amount of displacement is controlled by the amplitude and phase of the modes at the element level. This in turn facilitates reconfiguring the inter-element spacing at the array level. For instance, a uniformly-spaced array could be electronically transformed into a non-uniform one without any mechanical means. The proposed idea is demonstrated in two- and three-element linear antenna arrays. The technique has the potential to control the radiation characteristics such as sidelobe levels, position of the nulls, and the beamwidths in small arrays, which are useful for adaptively controlling the array performance in emerging wireless communication systems and radars.
