Coherence time3/20/2023 In long-distance transmission systems, the coherence time may be reduced by propagation factors such as dispersion, scattering, and. Such channel variation is much more significant in wireless communications systems, due to Doppler effects. 2003 – 2006, Development of Optical Clocks and Their Applications to Precision Frequency Measurements and Time Keeping (LX0454426), UWA, $37 597.00Ģ005- 2006, A Facility for Ultra-Precise Time and Frequency Transfer (LE0560710), UWA, $242 000.00Ģ003 - 2007, Creation of New Precision Optical and Microwave Technologies and their Application to Testing the Fundamental of Physics (DP0343391), UWA, $1 799 043.00Ģ006 - 2009, Developing New Clocks for Australia: Testing the Assumptions of Modern Physics (DP0662831), UWA, $649 819.00Ģ008 - 2012, Application of ultra-high stability cryogenic sapphire oscillators to Very Long Baseline Interferometry (LP0883292), $336 873.00Ģ010 - 2013, Precision time and frequency in the lab and in space to test fundamental physics (DP1092690), UWA, $789 923.00Ģ013-2015, Frequency standards with breakthrough performance: Engineering immunity to LO instabilities using dynamic error suppression (DP130103823), $45 000.00Ģ011-2015, Ground station facility for membership of the atomic clock ensemble in space mission (LE110100054), $1 230 000.00Ģ017 – 2018, Australian dark matter detector for high mass axions (LE180100042), UWA, $621 834.00Ģ019 – 2021, Precision low energy experiments to search for new physics (DP190100071), $557 909. For an electromagnetic wave, the coherence time is the time over which a propagating wave (especially a laser or maser beam) may be considered coherent, meaning that its phase is, on average, predictable. Coherence Time calculator uses Coherence Time 0.423/Maximum Doppler Shift to calculate the Coherence Time, The Coherence Time is the time duration over which the channel impulse response is essentially invariant.
