Railway and telecommunication companies have showed a great interest in deploying broadband mobile wireless networks in high-speed trains with the aim of supporting both provisioning of passenger services and automatic train control and signaling. This motivates the study of broadband wireless communications between a base-station transmitter and a mobile receiver whose antennas are placed on the...
The MAP and MMSE estimation of Laplace-distributed symbols transmitted over multiple-input multiple-output channels is studied. This is an important problem in analog joint source channel coding with spiral mappings, where the probability density function of the transmitted symbols approximates a Laplace distribution in the low SNR regime. Simulation results are presented to illustrate the suitability...
Modern wireless communication systems, such as WiMAX, rely on Orthogonal Frequency Division Multiplexing, a very robust modulation against frequency-selectivity, but very sensitive to time-selectivity, which is a typical feature in mobility scenarios. In this work, experimental measurements in real scenarios are carried out by employing WiMAX signals including the standard-compliant pilot signals...
