Statistical Modeling of Intelligent Transportation Systems Communication Channels

Intelligent Transportation Systems (ITS) is becoming an important paradigm, because of its ability to enhance safety and to mitigate congestion on road traffic scenarios. Realizing the fact that data collection scheme from in-situ test beds for large number of vehicles is always expensive and time consuming, before being employed in large scale,...

Single-receiver single-channel multi-frequency GNSS integrity: Outliers, slips, and ionospheric disturbances

In this contribution the integrity of single- receiver, single-channel, multi-frequency GNSS models is studied. The uniformly most powerful invariant test statistics for spikes and slips are derived and their detection capabilities are described by means of minimal detectable biases (MDBs). Analytical closed-form expressions of the phase-slip,...

A Study On Wavelet Packet Based Algorithm For Representation of Wireless Channel

Wireless telecommunication services are growing rapidly both in terms of the underlying technology as well as in the nature of the applications. The trends point to further growth in the foreseeable future. However, the dynamic nature of the wireless channel places fundamental limitations on the performance of wireless communication system....

A Study on Frequency Dependency and Spatial Modeling of Wireless Channels

Wideband channel measurements at 60 GHz in different environments

For future mobile multimedia communication, a Mobile Broadband System is in development, which operates at a frequency of 60 GHz. In order to get a better understanding of 60 GHz propagation effects in different environments with different conditions, several measurements were performed, using a spectrum analyzer and synthesized signal generator...

Performance analysis of hybrid DS/SFH system using analytical -and measured CODIT COST 207 channel model in the indoor environment

This report presents a performance analysis of hybrid DS/SFH CDMA system, by using analytical channel model as well as the CODIT COST 207 channel model. The use of code division multiple access scheme is considered in single and multiple pico cells. The performance is obtained by evaluating the bit error probability, throughput, and delay of the...

The feasibility study of a Hybrid DS/SFH CDMA radio systems is given in terms of bit error rate, throughput and delay, using an analytical -and measured CODIT COST 207 channel model. All results and evaluations presented are done considering the micro-cellular environment where the path gains are assumed to be Rician distributed in the case of...

An Analytical Performance Evaluation of a Coded OFDM-Based Transmission Scheme, using a Markov Model for a Frequency Selective Channel

In this report the performance of an error-correcting code on a wide-band frequency selective Rayleigh fading channel with an OFDM- based transmission scheme is estimated by means of an analytical model. In the European dTTb project, a transmission scheme for a new digital terrestrial TV system is under development. This scheme uses OFDM to...
