'The search for and ablility to find such a unified approach for problems dealing with evaluation of the performance of digital communication over generalized fading channels is what provided the impetus to write this book, the result of which represents the backbone for the material contained within its pages.'
2.s:The RAKE receiver performanceis significantly degraded in communicationover fast fading multipath channels Based on AWT and time and scale resolution ofa signal,this paper,via theoretical analysis and computer simulation,explores channel modeling andtheperformanceofthe time scale RAKE receiver,and makes contrast with traditional Rake receiver The simulation results indicate that it can work better than traditional Rake receiver in fast fading multi path channels
3.The receiver based on digital matched filter (DMF) is investigated extensively in order to study theperformanceofthe PN code acquisition over frequency-nonselective fading channel. By using the state transition diagram, the authors derive the analytic expressions ofthe mean acquisition time fora non-fading channel, a slowly fading channel anda fast fading channel.
7.A kind ofDigital Matched Filter using for Spread Spectrum Communication by VHSIC Hardware Description Language (VHDL) is designed. Its acquisition performancewhich provides new chances forthe design of Spread Spectrum signal processing chips is analyzed.
8.Sometimes, in the midst of his reading, no matter whatthebook might be which he had in his hand, he would suddenly fall into a profound meditation, whence he only emerged towritea few lines on thepagesofthe volume itself.
9.In this paper, a key state secondary vocational schools as a backdrop of young teachers within schools, thebackbone teachers, outstanding middle-level cadres lost their analysis, schools tofind out the brain drain key factors andits management of human resources existing problemsand propose appropriate countermeasures.
