Although many applications can be considered in the areas of radar and wireless communications, only one of them is detailed: high-resolution radar target imaging. The concluding remarks drawn in the final part of the paper are supported by simulation results performed on synthetic signals and by comparing the proposed methods to the scattering center extraction technique using the Fourier transform.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

To keep the handoff rate in this two-tier cellular system at an acceptable level, low mobility users (v<Vo) should undergo handoffs at microcell boundaries and high mobility users (v>Vo) should undergo handoffs at macrocell boundaries. The probability of erroneous assignment of a mobile to a microcell or macrocell is significantly lower than previous approaches. We analyze the optimal velocity threshold Vo and propose a dynamically adjusting method according to traffic load.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

It is necessary first to make a maximally flat group delay one-dimensional IIR filter with the proposed amplitude characteristic. A stable two-dimensional IIR transfer function is obtained using a digital spectral transformation. The way of obtaining the parameters for the digital spectral transformation is also given. This method does not need nonlinear optimization techniques. The obtained two-dimensional filter is guaranteed to be stable, the error between the specified passband contour is very small and the amplitude and group delay characteristic of the one-dimensional prototype are well preserved by the two-dimensional filter.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

Fourier descriptors are calculated in order to provide a good characterisation of the contour shape.
