“…As a result of the large amount of interest in the wireless channel, several probability density functions have been proposed [5], [6], [7], validated through measurements. First results were related to the temporal properties of the propagation environment, and finally, a focus in the angular power distribution motivated by the emerging MIMO systems has brought several models for the incident wave statistics.…”

Multipath propagation effect degrades usually the wireless system performances. Antenna Diversity in one of the several methods that have been studied to mitigate this phenomena. This technique can overcome the multipath fading improving the overall performance of communication system. In order to study the impact of the wireless channel and perform antenna diversity, two parameters must be evaluated: the mean effective gain, and the correlation coefficient between the antennas. Parallel Printed Dipole antennas have been succesfully used in mobile base station development, showing either broadband or multiple-band properties besides its low cost. However, polarization diversity parameters have not been analysed since these antennas have not been yet considered in mobile devices and diversity applications . In this paper, a polarization diversity schema comprised of two dual-printed dipole antennas for bluetooth and WIMAX applications operating in 2.4-2.4835 GHz and 3.5 GHz frequency bands are presented. Genetic Algorithm optimization (GA) is applied first, to a classical dual band printed dipole antenna schema, second to a pre-fractal tree parallel printed dipole to achieve a more compact radiator. Frequency performance of both antennas is introduced showing a VSWR< 1.5 for a input impedance of 50 Ohms. Later on, A diversity antenna based on the pre-fractal configuration is studied in terms of Mean effective gain (MEG) and correlation coefficient for indoor and outdoor scenarios. Results shows that MEG is nearly the same in both environments with a low correlation between the elements which means that diversity gain can be achieved using this schema.

“…Moreover, the co-prime array [ 9 , 10 , 11 ] is also a significant configuration which consists of two uniform sparse linear subarrays. The direction of arrival (DOA) plays an important role in the processing of signals from these vector sensor arrays, which can make full use of the polarization diversity of the impinging sources during the last decades [ 12 , 13 , 14 , 15 ]. The most representative joint DOA and polarization estimation methods are based on the subspace algorithms, including the polarized multiple signal classification (MUSIC) method [ 16 ] and polarized signal parameters via rotational invariance technique (ESPRIT) method [ 17 , 18 ].…”

This paper proposes a low-complexity method to estimate the direction of arrival and polarization based on the polarization sensitive array (PSA) which is composed of cross-dipoles. We built a half-quaternions model through the Cayley–Dickson form to remove the redundant information. Then, the directions of arrival (DOAs) were estimated via the root-MUSIC algorithm. Finally, the polarizations were estimated by generalized eigenvalue method. Unlike some existing searching algorithms, such as multiple signal classification (MUSIC), this method can avoid the peak searching and maintains high estimation accuracy. Moreover, we use the oblique projection operators to filter out the interference signals which are decoys of the target signal. Simulation results demonstrate the effectiveness and favorable performance of the proposed method.

“…Channel measurements with dual polarized transmissions are presented in [5]; in our measurements the polarization of the off-body antennas varies, due to changes in body posture of the rescue worker in action. The correlation of signals received by dual polarized antennas in an indoor environment was studied in [17]. In [14] measurements of a body-worn antenna system are performed in open space and the effects of a multipath environment are indirectly assessed.…”
