In classic analysis of capture effect, well-known expressions exist for the capture probabilities in the uplink of multiple-access wireless networks in Rayleigh fading channels. In this paper, we derive new analytical expressions for the average capture probabilities and PDFs of SIR in generalized (Nakagami-m) fading channels (capture model 1). The capture(More)
In this paper a performance analysis of modified M-ary phase-shift-keying (MPSK) signal diversity receiver with predetection equal gain combiner (EGC) will be presented. The modification is in introducing a structure that performs the estimation with remodulation (ER). The EGC combining is realized by using the constant modulus algorithm (CMA). The(More)

In this paper is analyzed capacity and rate improvement due to cooperation in a network where cooperating terminals are close together. Cooperation between terminals is used for minimizing fading induced by multipath propagation in wireless networks. The cooperation techniques exploit space diversity available through cooperating terminals' relaying signals(More)
In this paper, we analyzed performance of DSSS/DPSK system in the presence of packet PSK interference. The results show that the proposed reconfiguration circuit decreases the error probability for at least an order of magnitude, compared to the system using only ¿-structure.
In this paper we consider a UWB radio system performance using pulse position modulation in the presence of various types of interferences. Interference rejection using adaptive transversal filter, as well as the range of the interference rate where the use of the filter is required, is considered in this paper
A novel multiple symbol differential detection (MSDD) for M-ary differential phase shift keying (MDPSK) system is proposed in this paper. The symbol error probability and the influence of the varous receiver's parameters on the error probability are analysed in the presence of the carrier frequency offset. The theoretical symbol error probability is derived(More)
In this paper, an algorithm for three dimensional direction of arrival estimation is proposed. The proposed algorithm is presented using model of the mobile receiver having three antennas. It is shown that the proposed algorithm is able to track both azimuth and elevation by forming two S-curves, if the initial direction of arrival estimate is within a(More)
