Multipath is known to be one of the most dominant sources of accuracy degradation in Global Navigation Satellite System, especially in high-precision positioning applications. It’s too difficult to mitigation this error in satellite navigation system. However, with the development of the nonlinear filtering theory, it provides a new approach to solve this issue. In the

With the urban rail being constructed and developed continuously at home and abroad, it has become a very important part of public transport in large cities. Since the number of urban rail path is adding constantly, the routes that the passenger go to the destination become more and more. Study behavior routes being chosen by

As early as in the 1960s software crisis initial period, along with software function’s growth, the people realized that is high to the software order of complexity, the development cycle is long, the reliability is bad, development and maintenance cost big and so on questions. And the reliability bad is the concentrated expression of software

1.IntroductionThe target of broad band wireless communication is to transmit data fast andreliably, while there are two tough problems in front of us, they are multipath fadingchannel and bandwidth efficiency. In Orthogonal Frequency Division Multiplexing(OFDM) system, a high-rate serial data stream is split into many low-rate parallelstreams, thus changed the frequency selective multipath fading channel
