An Adaptive tranSmission mechanism exploiting both interference loCality and the relationship between dEsired sigNal and inTerference (ASCENT) is proposed for uplink transmission in heterogeneous networks. The authors adopt both X channel and Z channel models according to which spatial signal processing is designed. In the X channel, the picocell base station (PBS) exploits information the macr...

Powerline interference always disturbs recordings of biomedical signals. Numerous methods have been developed to reduce powerline interference. However, most of these techniques not only reduce the interference but also attenuate the 60 Hz power of the biomedical signals themselves. In the present study, we applied the S-transform, which provides an absolute phase of each frequency in a multi-r...

In this paper, we focus on the design of transmit waveforms a frequency diverse array (FDA) in order to improve output signal-to-interference-plus-noise ratio (SINR) presence signal-dependent mainlobe interference. Since classical multi-carrier matched filtering-based FDA receiver cannot effectively utilize waveform diversity FDA, novel framework based multi-channel mixing and low pass filterin...

We provide a general overview of the recent development on the constrained group decoder (CGD) for interference channels. We first consider the CGD for a simple system of interference channels with no feedback from the receivers to the transmitters, where the transmitters employ fixed-rate channel codes and modulation schemes. We provide simulation results to show that, compared with the interf...

A method utilizing the cyclic spectral analysis (CSA) and reduced-rank multistage Wiener filtering (RRMSWF) algorithm to mitigate the interference for the GPS receiver is proposed. In many cases, interference from adjacent channel or from cochannel overlaps on the weak global positioning system (GPS) signal in both time and frequency domains, and it is hard to mitigate this kind of strong inter...

Ship detection in heavy sea clutter is a big challenge for over-the-horizon (OTH) radar. Wideband signal is helpful for improving range resolution and the signal-to-clutter ratio. In this paper, to support OTH radar employing wideband in cochannel interference, we propose environmental sensing-based waveform (ESBW) strategy, by considering transmit waveform design as an active approach and cogn...

This paper considers adaptive detection and steering estimation in the presence of useful signal and interference mismatches. We assume a homogeneous environment where the random disturbance components from the primary and secondary data share the same covariance matrix. Moreover the data under test contains a deterministic interference vector in addition to the possible useful signal. We focus...

In this paper, we propose an enhanced leakage-based precoding scheme, i.e., layer signal to leakage plus noise ratio (layer SLNR) scheme, for multi-user multi-layer MIMO systems. Specifically, the layer SLNR scheme incorporates the MIMO receiver structure into the precoder design procedure, which makes the formulation of signal power and interference / leakage power more accurate. Besides, the ...

Narrowband radio transmitters like radio amateurs and broadcast radio stations are considered to be a serious problem for highbitrate data transmission over twisted pairs. Due to its high power level, radio frequency interference (RFI) has the potential of overloading the receiver’s analog-to-digital converter (ADC). Once the ADC is in saturation, any countermeasure taken in digital domain will...
