Time-Domain Spread Modulation in Radio-over-Fiber Systems for Robust Low-SNR Hardware Compensation

In radio-over-fiber (RoF) systems, digital signal processing (DSP) is concentrated at the central station, leaving the remote antenna unit with only a power amplifier and an antenna. Cost-constrained commercial-grade components along the signal chain introduce nonlinear impairments that degrade the effective signal-to-...

A Blind Architecture for Signal Combining in Distributed Satellite Communications

To meet the increasing demand for high data rates in satellite communications (SATCOM), the requirements in terms of link quality and reliability are also increasing. Reception of SATCOM signals with multiple ground stations and combining them to increase the signal-to-noise ratio (SNR) provides a flexible and robust a...

Sampling-Level Time-Division Multiplexing for Fully Connected MIMO Transmitters: Principle and Prototype Verification

Multiple-input multiple-output (MIMO) systems and multibeam phased arrays are essential for modern wireless communications. Conventional fully connected (FC) beamformers achieve the maximum array gain but rely on cross-connection networks with numerous phase shifters, leading to high power consumption and implementatio...

Physical Layer Modulation Schemes in Inter-Satellite Laser Communication

Due to the demand for high data capacities, space networks rely on satellite constellations. Inter-satellite laser communication can meet this need. Nevertheless, space channels still have spatial and dynamic impairments. In this paper, physical layer modulation schemes for these optical links are evaluated. Intensity...
