Most importantly, our team are famous for much research on ecology, physiology,molecular phylogenesis of bats at home and abroad, we have gained much originative result in this field, and we firstly found and studied the third piscivorous bat, Myotis ricketti.We provide evidence that the species Myotis ricketti is piscivorous, and close negative relationships were found firstly within Rhinolophidae and Hipposideridae between call frequency and ear length. Some species of taxology status in rhinolophidae were studied by molecular phylogenesis; phylogenesis relationship between rhinolophidae and hipposideridae and different populations of miniopterus schreibersii were also studied; we also studied Social structure of Tylonycteris pachypusa and T. robustula and the isolating mechanisms of ecological niches.

As a result, there are no specific advantages of processing signals in frequency domain, and we propose to directly process signals in time domain. By this way, it is observed that in time domain the signal signatures can be arranged into groups of orthogonal components, leading to a very natural group-wise symbol recovery scheme. To realize this figure of merit, we propose a GSC-based receiver, which also takes into account the mitigation of channel mismatch effects caused by the channel temporal variation and the imperfect estimation.
