“…In [26], the clustering effect is not observed and the probability of receiving a multipath component, within discrete excess delay intervals of 7.8 ns wide, is approximated with piecewise functions. In [17] a measurement campaign at 39 and 60 GHz in an outdoor environment is presented. A model based on a non-stationary Poisson process is proposed.…”

Abstract-In order to make realistic simulations of the radio propagation mechanism in ultra-wide band channels, an appropriate model is usually needed. In this paper we give a new technique of modeling the impulse response of the 60 Ghz channel. This new approach is based on the spectral analysis of α-stable processes. Our new model present many advantages : firstly, the channel is characterized only by a one deterministic function(spectral density) in the place of four parameters. Secondly, the estimations procedures deals directly with the measured transfer functions this avoid loosing informations in data pretreatments. Finally, an estimation of the spectral measure permit to directly generate the impulse response.

“…The variation with respect to the slower uctuations, the t domain, will de ne the rate at which synchronisation, equalisation and other signal processing techniques can track the time-variant channel. Amongst others, Wales [5] and Spindel [4] have investigated the properties of microwave and acoustic communication delay spreads in the 1: domain. There are however few published practical results for typical shallow-water acoustic communication channels.…”

This paper presents the experimental set-up, geometry and environmental conditions for pulsed channel soundings in the Mediterranean Sea. A short five-cycle pulse at a transmit frequency of 50 kHz is utilised to probe the ocean channel at a high repetition rate. The fast uctuations due to re ection and scattering are recorded on a transient analyser. The mean and coef cient of variation are used to analyse the pulsed response over a short period of time. Typical energy spreads induced by boundary re ection and scattering are in the region of 3 to 4 ms and could conceivably introduce inter-symbol interference in an underwater telemetry system where high bandwidth ef ciency is required.

“…Over the last three decades, the 60 GHz millimetre-wave wireless channel has been thoroughly investigated and characterised with a significant number of publications based on CW transmission and channel sounding measurements and modelling [7][8][9][10][11][12][13] for indoor and outdoor environments. SC-FDE scheme has been extensively investigated and their performance over the 60 GHz dispersive channels was evaluated through simulation [4,5,[14][15][16][17].…”

Single‐carrier transmission with frequency domain equalisation (SC‐FDE) is one of the candidates for the next generation indoor wireless personal area networks operating at millimetre waves in the frequency band around 60 GHz. In this study, a 64.8 GHz SC‐FDE wireless mobile radio system is presented and its back‐to‐back performance verified. The transceiver employs fractionally spaced minimum mean‐square‐error frequency domain equalisation, that is, compliant with the IEEE 802.15.3c millimetre‐wave standard. Results of experiments, undertaken at 64.8 GHz in a number of indoor environments, to characterise the effectiveness of the SC‐FDE technique to mitigate the effects of multipath propagation are presented for line‐of‐sight and non‐line‐of‐sight scenarios. Bit‐error‐rate performance for 16‐quadrature amplitude modulation 100 Mb/s transmission is given as a function of signal‐to‐noise ratio for a combination of omnidirectional and directional antennas at both terminals and compared with that obtained in additive white Gaussian noise channel.
