This paper presents a sensitivity analysis of filter bank multicarrier (FBMC) systems to carrier frequency offset (CFO) and timing offset. Although the emphasis of the paper is on the class of FBMC systems that are based on offset quadrature amplitude modulation (OQAM), the developed results are found applicable to cosine modulated-based FBMC systems as well. We assume that coarse CFO and timin...

Future military waveforms are most probably implemented on software defined radios capable to handle several waveforms. Implementation of several waveforms would require design of several receiver chains. In order to ease these design tasks, this paper describes a universal frequency domain baseband receiver structure. The structure may be used as a starting point to design receiver basebands f...

Optical communication refers to the mode with optical signal as a carrier [...]

We develop the concept of quantum carrier and show that messages can be uploaded and downloaded from this carrier and while in transit, these messages are hidden from external agents. We explain in detail the working of the quantum carrier for different communication tasks, including quantum key distribution, classical secret and quantum state sharing among a set of n players according to gener...

In this paper we consider physical-layer network coding (PLNC) in OFDM-based two-way relaying systems. Practically, a key impairment for the application of PLNC is the carrier frequency offset (CFO) mismatch between the sources and the relay, which can not be compensated completely in the multiple-access (MA) phase. As this CFO mismatch results in inter-carrier interference (ICI) for OFDM trans...

To equalize such long fading channel traditional single carrier time domain equalization becomes infeasible due to its large computational complexity. Single-carri...

We present LoRea an architecture consisting of a backscatter tag, a reader and multiple carrier generators that overcomes the power, cost and range limitations of existing backscatter systems such as Computational Radio Frequency Identification (CRFID). LoRea achieves this by: First, generating narrow-band backscatter transmissions. Second, by mitigating self-interference without the complex de...

Hidden Markov model methods for stochastic sequential analysis are described and a synergistic union is presented to arrive at a new form of carrier-based communication, where the carrier is not periodic but is stochastic, typically with stationary statistics. HMM with binned duration, and meta-HMM algorithmic methods, are shown to enable practical stochastic carrier wave encoding/decoding, whe...

This paper initiatively puts forward a novel synthesis design for generating UWB narrow pulse by using CI (Carrier Interference) subcarrier waveform synthesis and Bessel function expansion. Through adaptively adjusting the initial phases of multiple subcarriers according to the location information, CI (Carrier Interference) sub-carrier waveform synthesis signal could achieve better performance...

Much research has been devoted to synchronization and chaos-based communication in the last two decades or so. Since the early 1990s, many papers have addressed the subject, and much progress has been made. Considering that the research has been developed in many different – and, at certain extent, complementary – directions, it would be interesting to outline the advances and establish the bot...
