On the scheme of delay-waiting direct rapid acquisition of very long PN code by WANG Hao, YI Da-jiang, WANG Fei-xue, ZHUANG Zhao-wen

“…A scheme of direct rapid acquisition of very long PN code that was used in satellite navigation system based on DSSS was presented.In the scheme,the delay of the local PN code was determined through estimate the clock bias between local satellite clock,and which is used to preset the match filter.The scheme was so called “delay-waiting” method.The deeply analysis on technique details and acquisition performance of the scheme is given.…”

Tractable yet effective approximation to directional antenna array for millimeter-wave networks by Na DENG, Haichao WEI

“…The complexity of the actual antenna pattern imposes restrictions on investigating the benefits of directional antenna arrays in large-scale networks.Hence,a novel multi-level flat-top antenna pattern was proposed to approximate and simplify the actual one and was applied in millimeter-wave cellular networks for performance analysis.To fully characterize the impact of the directional antenna array on the user performance,stochastic geometry was adopted to establish an analytical framework for millimeter-wave cellular networks and derive the coverage probability and transmission rate of the typical user with the proposed multi-level flat-top antenna pattern,including the exact and bounding expressions.The simulation results show that the proposed antenna pattern provides a better tradeoff between the accuracy and tractability than previous patterns.…”
