نویسندگان

چکیده

This paper analyzes the performance of sample matrix inversion (SMI) filter used by antenna array receivers in pulse interference environment. Firstly, from perspective comparison, it is proved that theoretical optimal signal to noise ratio (SINR) SMI under same with continuous interferences. Then convergence characteristics are deduced, and relationship between speed length training samples duty interferences given. Finally, results simulation consistent those numerical analysis, which verifies correctness analysis. The show decreases interference, needs more suppress effectively.

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Performance of antenna array receiver algorithms for CDMA

This paper considers a number of algorithms that could be used for antenna array receivers in the mobile–to–base station link of a cellular code division multiple access (CDMA) system. Two classes of algorithms are considered: 1) algorithms that estimate spatially matched filter solutions and 2) adaptive techniques for suppressing interference. In the simulations that were conducted, the “match...

Asymptotic performance of blind antenna array receiver algorithms for CDMA

This paper considers the performance of four channel identi cation techniques for code division multiple access (CDMA) antenna array receivers. These techniques are based on the assumption that the interference is spatially white: they provide a spatial \matched lter" solution. Perturbation formulae are presented for estimating the attainable signal to interference and noise ratios (SINR) for t...

Interference Mitigation of Replay Attacks in GPS Receiver using of Finite Impulse Response Filter

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...
