Multiplexing cell‐cell communication

Modulation and multiplexing in optical communication systems

Digital electronics and optical transport The rapid transition from analog to digital systems over the past ~50 years has enabled universal processing of all kinds of information, fundamentally without loss of quality [1]. Breakthroughs in digital semiconductor technologies and their enormous ability to scale [2] have enabled cost-effective mass-production of richly functional yet highly reliab...

Coherence multiplexing for optical communication systems

Adaptive Statistical Multiplexing for Broadband Communication

Statistical multiplexing requires a decision function to classify which source combinations can be multiplexed through a given packet network node while meeting quality of service guarantees. This chapter shows there are no practical fixed statistical multiplexing decision functions that carry reasonable loads and rarely violate quality of service requirements under all distributions of source ...

Quadrature Amplitude Modulation All Optical Orthogonal Frequency Division Multiplexing-dense Wavelength Division Multiplexing-optical Wireless Communication System under Different Weather Conditions

This paper proposes an analytical model for evaluating the performance of dense wavelength division multiplexing (DWDM) for all optical orthogonal frequency division multiplexing (AO-OFDM) optical wireless channel. The investigated performance for proposed system is evaluated for the parameters  bit error rate (BER) and Q factor .The constellation diagrams, and bit error rate (BER) of the recei...

High-speed acoustic communication by multiplexing orbital angular momentum.

Long-range acoustic communication is crucial to underwater applications such as collection of scientific data from benthic stations, ocean geology, and remote control of off-shore industrial activities. However, the transmission rate of acoustic communication is always limited by the narrow-frequency bandwidth of the acoustic waves because of the large attenuation for high-frequency sound in wa...
