— For the design of an OFDM train communications system it is essential to characterise and consider the channel parameters. The transmission channel of a high-speed train scenario is frequency selective as well as time variant. Thus, delay spread and Doppler spread are investigated as crucial parameters for the OFDM system performance. Using a ray-tracing(More)
– This paper is concerned with the calculation of the aggregate interference power from ultra-wideband devices received by a point to point communication system. The source based model for the aggregate interference power and its parameters are presented together with results for different sets of the parameter values. The results show that the applied wave(More)
