Fundamentals of Channel Emulation - octoScope
Fundamentals of Channel Emulation Mar-2012 Outline What is Channel Emulation and why is it critical for MIMO systems? Channel modeling standards and technologies Channel model statistics MIMO/OTA Channel emulator implementation Competitive analysis 2 Wireless Channel Frequency and time variable wireless Channel Multipath creates a sum of multiple versions of the TX signal at the RX Mobility of reflectors and wireless devices causes Doppler-based fading Multiple antenna techniques are used to optimize transmission in the presence of multipath and Doppler fading 3 Channel Quality MIMO=multiple input multiple output Multipath and Flat Fading In a wireless Channel the signal propagating from TX to RX experiences Flat
