There are three multiplexing schemes for Multi-Input MultiOutput (MIMO) channel sounder Time-division multiplexing (TDM), Code-division multiplexing (CDM) and Frequencydivision multiplexing (FDM). The purpose of this paper is comparison overview of multiplexing schemes for MIMO channel sounder. In this paper TDM, FDM and CDM techniques for MIMO channel sounding are considered. TDM, FDM and CDM ...

Color metasurface holograms are powerful and versatile platforms for modulating the amplitude, phase, polarization, other properties of light at multiple operating wavelengths. However, current color holography can only realize static manipulation. In this study, we propose demonstrate a multiplexing technique combined with multiwavelength code-division (CDM) to dynamic Multicolor code referenc...

Nitrogen-vacancy color centers can perform highly sensitive and spatially resolved quantum measurements of physical quantities such as magnetic field, temperature, pressure. Meanwhile, sensing so many variables at the same time often introduces additional noise, causing a reduced accuracy. Here, dual-microwave time-division multiplexing protocol is used in conjunction with lock-in amplifier ord...

Optical camera communication (OCC) is a type of visible light that employs as the receiver. Various flicker-free OCC methods using general-purpose low-frame rate have been proposed. In particular, undersampling method uses short exposure and light-emitting diode blinks faster than camera's frame rate. Despite time, transmitter has to send symbol for period or longer because relationship between...

LEACH is a routing protocol based on clustering in wireless sensor networks and is based on a low power adaptive hierarchical routing algorithm design of wireless sensor network. Time division multiplexing mechanism is for each wireless sensor network node distribution independent time slots for data transceiver, and the node into sleep state in other free time slot. This paper introduces MAC p...

ÐIn this paper, we study distributed path reservation protocols for multiplexed all-optical interconnection networks. The path reservation protocols negotiate the reservation and establishment of connections that arrive dynamically to the network. These protocols can be applied to both wavelength division multiplexing (WDM) and time division multiplexing (TDM) networks. Two classes of protocols...
