MIMO Beamforming in Millimeter-Wave Directional Wi-Fi
Keang-Po Ho, Shi Cheng, Jianhan Liu
Beamforming is indispensable in the operation of 60-GHz millimeter-wave directional multi-gigabit Wi-Fi. Simple power method and its extensions enable the transmitting and receivin…
Wavelength-Selective Switches for Mode-Division Multiplexing: Scaling and Performance Analysis
Keang-Po Ho, Joseph M. Kahn, Jeffrey P. Wilde
Wavelength-selective switches for mode-division-multiplexing systems are designed by scaling switches from single-mode systems. All modes at a given wavelength are switched as a un…
Exact Model for Mode-Dependent Gains and Losses in Multimode Fiber
Keang-Po Ho
In the strong mode coupling regime, the model for mode-dependent gains and losses (collectively referred as MDL) of a multimode fiber is extended to the region with large MDL. The…
Frequency Diversity in Mode-Division Multiplexing Systems
Keang-Po Ho, Joseph M. Kahn
In the regime of strong mode coupling, the modal gains and losses and the modal group delays of a multimode fiber are known to have well-defined statistical properties. In mode-div…
Mode-Dependent Loss and Gain: Statistics and Effect on Mode-Division Multiplexing
Keang-Po Ho, Joseph M. Kahn
In multimode fiber transmission systems, mode-dependent loss and gain (collectively referred to as MDL) pose fundamental performance limitations. In the regime of strong mode coupl…
Statistics of Group Delays in Multimode Fiber with Strong Mode Coupling
Keang-Po Ho, Joseph M. Kahn
The modal group delays (GDs) are a key property governing the dispersion of signals propagating in a multimode fiber (MMF). A MMF is in the strong-coupling regime when the total le…
