This paper presents an iterative bit and power allocation algorithm for OFDM Multiple-Input Multiple-Output (MIMO) system in frequency selective fading channels and uses V-BLAST as a detection algorithm. Assuming knowledge of the instantaneous channel gains for all spatial channels at all the subcarriers in the receiver, bit and power is assigned to each(More)
Direct volume rendering has been an important technique for visualizing volume data. An unobstructed view on the inspected features of interest can help the user to get the insight of the volume data being explored. In this paper an exploratory volume visualization framework named ProbeVolume is presented. Probe-Volume provides a moveable and sizeable(More)
