Low power consumption and high data rate are the most important requirements for the communication system. Especially, very low power consumption modulation method is required for the short range communication systems such as the medical implantable communication devices or capsule endoscope, and so on. For the higher data rate, we like to combine the OFDM system into the QAPM since the OFDM sy...

The current state of the telecommunications market exhibits a high potential to absorb efficient innovations in wireless connectivity, especially those that can be applied Internet Things and similar domains. Contributing direction, this paper describes design implementation fully differential impulse-radio ultra-wideband (IR-UWB) transmitter using pulse-amplitude modulation, with an adaptive p...

An integrated electro-optic modulator based on a waveguide Bragg grating in thin-film lithium niobate is introduced. The compact device with footprint of 10 × 400 ?m2 displays an optical extinction ratio 53.8 dB at wavelength 1555.9 nm the C-band. With simple intensity modulation and direct detection scheme, data rates up to 100 Gbit/s are demonstrated 2-, 4- 8-level pulse-amplitude formats. fi...

There are a lot of ways to achieve large current pulse power supply, and the more common way is to adopt the inverter switching circuit to achieve pulse power supply. The core of the NC power supply design of large current and wide frequency pulse in SEAM is using two-stage modulation. Combined with inverter technology, DC chopper technology and NC technology, it not only can achieve the adjust...

The commingled microbial moiety of oxygenic photogranules (OPGs) facilitates aeration-free wastewater treatment. Embedded in an extracellular polymeric substances (EPS) matrix, producers and consumers oxygen occupying granular niches exchange substrates among themselves with the bulk fluid. An assessment OPG’s phototrophic potential or functional capacity may require combining different photoac...

In this thesis, we are trying to optimize the tradeoff between the receiver complexity and its performance for two modulations currently used in aeronautical telemetry. A reduced complexity detector is of interest because it reduces the implementation cost. The Pulse Amplitude Modulation (PAM) representation of Continuous Phase Modulation (CPM) signals typically results in reducedcomplexity det...

Bilateral cochlear implantation seeks to improve hearing by taking advantage of the binaural processing of the central auditory system. Cochlear implants typically encode sound in each spectral channel by amplitude modulating (AM) a fixed-rate pulse train, thus interaural time differences (ITD) are only delivered in the envelope. We investigated the ITD sensitivity of inferior colliculus (IC) n...
