— This paper describes a model for mobile radio channels that includes consideration of directions of arrival and is thus suitable for simulations of the performance of wireless systems that use smart antennas. The model is specified for 13 different types of environments, covering macro-micro-and picocells. In this paper, a hierarchy of modeling concepts(More)
– A stochastic radio channel model (SRCM) for broadband indoor mobile systems operating at 5.2 and 17 GHz has been derived within the ACTS project AC085 Magic WAND. The SRCM was designed to accurately describe the time, frequency, direction, and polarization dispersive characteristic of real radio channels because these effects are important for the design(More)
|A demodulation algorithm for a base station receiver in a direct sequence (DS) spread spectrum code division multiple access (CDMA) communication system is proposed which performs joint multiuser detection and estimation using the output signals of an antenna array in the absence of a tight power control. The scheme is a combination of a multistage (MS)(More)
This paper presents results of a measurement campaign carried out at a carrier frequency of 24 GHz in indoor non-line-of-sight (NLOS) scenarios. The received signal is resolved with respect to the delays, azimuths, elevations, and complex amplitudes of the incident waves. A clustering pattern in both delay and angle of arrival is visible in the data.(More)
A novel wideband channel sounding system operating at 24 GHz with an RF bandwidth of 1 GHz is presented. The SAGE (space-alternating generalized expectation maximization) algorithm is used for obtaining high-resolution estimates of the parameters characterizing the impinging waves, i.e. the delays, incidence azimuths, incidence elevations and complex(More)
This document describes a general proposal for combining all relevant effects of the directional mobile radio channel. Effects included are pathloss, shadowing, small-scale fading due to interference, joint delay and azimuth spreading. The latter accounts for the clustering nature of the channel when observed with wideband and/or directionally resolving(More)
This paper summarizes the achievements of Subworkinggroup 2.1 (SWG2.1) of the COST259 initiative. A common approach for modelling the time-variant wideband angular-dispersive radio channel for link-level simulations is derived and the main parameters are described. The basic modelling philosophy is a stochastic signal description where deter-ministic(More)
Employing dual antenna interference suppression techniques in GSM 8PSK downlink, " in Proc. ABSTRACT In 3GPP GERAN 1 , the performance specification of dual-antenna interference suppression techniques will be a subject of the Downlink Advanced Receiver Performance (DARP) phase II work item. In this study, we apply a filter-based single antenna interference(More)
