__ One of the main assumptions in the Clarke's classic channel model is isotropic scattering, i.e. uniform distribution for the angle of arrival of multipath components at the mobile station.However, in many mobile radio channels we encounter non-isotropic scattering, which strongly affects the correlation function and power spectrum of the complex envelope at the mobile receiver. In this contribution, we propose the use of the versatile von Mises angular distribution, which includes and/or closely approximates important distributions like uniform, impulse, cardioid, Gaussian, and wrapped Gaussian, for modeling the non-uniform angle of arrivals at the mobile. Based on this distribution, associated correlation function and power spectrum of the complex envelope at the mobile receiver are derived. The utility of the new results is demonstrated by comparison with the correlation function estimates of measured data.

“…Destructive AWGN (17 dB, lines L ) causes a small number of very long bursts for low Doppler spreads whereas a large number of shorter bursts are produced for high Doppler spreads. However, the number of symbol errors is about the same in both cases [19]. For higher values of E /N (30 dB, lines L ), where AWGN is not the most signi"cant factor of distortion, the performance is di!erent, because the bursts are very short for any Doppler spread and are mainly due to the strong amplitude attenuation and the fast phase inversion.…”

SUMMARYIn this paper the performance of a concatenated coding scheme is evaluated over a slow Rayleigh fading HF ionospheric link with additive white Gaussian noise (AWGN). Well-known Ungerboeck TCM techniques onto an 8-PSK signal set are used as inner codes and Reed}Solomon block codes as outer codes. The coded/modulated signal is further di!erentially encoded before transmission to combat random phase changes. Block interleaving techniques are necessary to randomise long bursts of errors caused by the fading channel. The performance of the proposed concatenated coding system is investigated for various Doppler spreads. Signi"cant coding gains are achieved over uncoded, diversity or other conventionally coded systems with a small bandwidth expansion. Finally the interesting e!ects of interleaving on the behaviour of the proposed systems are analysed.

A unified three-dimension probabilistic model is presented to describe multipath phenomena in various built-up areas with randomly distributed buildings placed on rough terrain. The joint information regarding angle-of-arrival and time delay spread is obtained through study of the main propagation mechanisms in urban wireless communication channels. Comparison with other models and with measurements carried out in different urban environments is presented. It is shown that in dense urban areas the distribution of the obstructions surrounding the base station and the moving vehicle, as well as the elevations of both antennas contribute to the signal power profiles in the space and time domains. Using a combination of the statistical description of the built-up terrain and the 3D deterministic approach based on Kirchhoff approximation, the effects of scattering and diffraction phenomena on signal power spatial and temporal distribution are examined.
