With the development of space communication systems, the transferred data have varied from traditional asynchronous data to mixed data of synchronous and asynchronous data. Synchronous data, such as video and audio, need to be transmitted in high real-time while asynchronous data, such as image, command and file, need not to be transmitted in high(More)
In view of the existing fire distribution algorithm without considering the coordination of firepower units and not giving the precise number of assigned, we proposed one multi-target fire distribution strategy based on improved genetic algorithm. We established the optimizing fire allocation model of air defense missile, designed its multitarget fire(More)
According to the characteristics of underwater acoustic channel, Thorp experience formula is adopted in order to simulate seawater absorption properties, on the basis of which, the path loss is solved by means of simulation. A Wenz model is also improved so as to approach the noise model of underwater acoustic channel better. Furthermore, OPNET platform(More)
Binary Offset Carrier (BOC) modulated signal has multi-correlation peaks, whose S curve of Phase Detector (PD) having several cross-zero points, this can lead to do error judge on receiver tracking. So, a new tracking algorithm is proposed in this paper, it using the quadratic BOC to removing the effect of several cross-zero points on S curve. The comparing(More)
A new wideband direction-of-arrival (DOA) estimation approach based on frequency-domain frequency-invariant beamformers(FDFIBs) is proposed. It is able to resolve correlated source signals and can be applicable to arrays of arbitrary geometry without preliminary DOA estimate. The method of wideband adaptive beamforming based on DOA information is proposed.(More)
A new wideband direction-of-arrival (DOA) estimation approach based on frequency-domain frequency-invariant beamformers (FDFIBs) is proposed. It is able to resolve correlated source signals and can be applicable to arrays of arbitrary geometry without preliminary DOA estimate. A set of frequency-domain beamformers with constant mainlobe and lower sidelobes(More)
Satellite handover happens frequently in Low Earth Orbit (LEO) satellite network due to satellite’s high mobility. In this paper, we propose a novel call admission control scheme which utilizes both the geographical information and the distance between the new call’s position and the preparing handover user’s position in the previous plot beam to(More)
According to the nonlinear amplification characteristic with memory effection of power amplifier (PA) inWCDMA systems, digital predistorter model is established and an identification algorithm for Wiener PA model with memoryis proposed. The method can avoid the local convergence problem of NG algorithm effectively. Moreover it has a very good suppression of(More)
The factors such as hardware malfunction and invasion, can lead to the nodes and edges failure of Command and Control (C2) network, which divide the original connected network topology, even result in global network damage. To assess the invulnerability of the C2 network dynamically, this study has proposed a measurement of invulnerability for C2 network(More)
With the development of navigation signal in direct spread spectrum communication, in order to accurately receive the signal, it¿s important for processing pseudo code phase in the receiver. Simultaneity, precision demodulation is required to do in the synchronization process in receiver. nevertheless, as the appearance of new signal with new(More)
