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-...
