Time Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملIncreasing System Throughput by Time-Varying Beamforming in Multiuser Systems with Slowly Varying Fading Channels
We analyze a cellular communication system in which a basestation or access point equipped with several antennas transmits packet data to several mobile data users by means of a TDMA scheme. A scheduler in the basestation uses knowledge about the instantaneous channel quality (signal to noise ratio, SNR) of all users to allocate the channel resource to the user which maximizes a certain metric....
متن کاملSound Propagation in Slowly Varying 2D Duct with Shear Flow
Sound propagation in uniformly lined straight ducts with uniform mean flow is well established by its analytically exact description in duct modes [1, 2, 3]. In cross-wise nonuniform flow there are still modes, although the (Pridmore-Brown) equation that describes them is in general not solvable in terms of standard functions [4, 5, 6, 7, 8, 9] and has to be solved numerically. These modal solu...

متن کاملAn Implementation of Discrete Multi-Tone over Slowly Time-varying Multiple-Input/Multiple-Output Channels
Recent analysis of Multiple-Input Multiple-Output (MIMO) communication systems, for example those involving antenna arrays, has shown that channel capacity increases linearly with the number of antennas. This motivates the investigation of methods for data transmission over slowly time-varying MIMO channels. A low complexity method is introduced that e ectively diagonalizes the MIMO channel. Th...
