The implementation of OFDM-based systems suffers from impairments such as in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the radio frequency (RF) signal and can be pr ...
The results of a range of experimental characterization exercises of interferometric noise for the case of a representative 2-D time-spreading wavelengthhopping optical code family are presented. Interferometric noise is evaluated at a data rate of 2.5 Gbi ...
This paper discusses a novel tag/reader system, based on the passive, far-field RFID principle, with megabits per second read capability at operating ranges of several centimeters. The system operates in the ISM band at 2.45 GHz. A maximum data rate of 4 M ...
A high-order discontinuous Galerkin finite element method, on triangular elements, is used to model piezoelectric systems. Non-destructive testing problems are Studied. In particular, flex circuit transducer designs which can be used to obtain information ...
OFDM systems are susceptible to receiver impairments such as IQ imbalance and phase noise. These impairments can severely degrade the achievable effective signal-to-noise ratio at the receiver. In this paper, we propose a joint compensation scheme to mitig ...
Phase noise causes significant degradation in the performance of orthogonal frequency division multiplexing (OFDM)-based wireless communication systems. The presence of phase noise can reduce the effective signal-to-noise ratio (SNR) at the receiver, and c ...
An achievable bit rate per source-destination pair in a wireless network of n randomly located nodes is determined adopting the scaling limit approach of statistical physics. It is shown that randomly scattered nodes can achieve, with high probability, the ...
This paper studies the specifications of gated-oscillator-based clock and data recovery circuits (GO CDRs) designed for short haul optical data communication systems. Jitter tolerance (JTOL) and frequency tolerance (FTOL) are analyzed and modeled as two ma ...
In this paper, the bit error rate (BER) performance for an ultra-wide bandwidth (UWB) impulse radio in an additive white Gaussian noise (AWGN) transmission channel and with Gaussian jitter is estimated. The assumed receiver combines the received pulses to ...
Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive model to approximate Hilbert envelopes in frequency sub-bands for relatively long temporal segments. Although the basic technique achieves good quality of the reconstructe ...
