The receiver of base station receives radio wave signals in different paths or directions, having different multi-path delays and amplitude attenuations. The envelope of the signal received is similar to the Rayleigh distribution in the application surrounding of 3G, and the multi-path propagation fading (MPF) would be induced, which will degrade the performance of the receiver. Especially, the different...
The direction of arriving (DOA) estimation algorithms used in TD-SCDMA system to realize DOA detection would result in a large number of mathematical operations. Meanwhile, the number of DOA detection would be restricted by the number of array elements of a smart antenna. To solve this problem, a new method for DOA detection based on the orthogonal mid-amble sequence would be presented in this paper,...
Tri-generation system is efficient in supplying thermal energy and electricity. But it is very difficult to satisfy multiple load demands simultaneously in real applications. Therefore, the benefit of tri-generation system is not so easy to realize. If the electric load is separated from the thermal load, difficulty of control would be avoided. In this work, combined cooling and heating (CCH) mode...
