The purpose of the study was to evaluate the influence of selected physiological parameters on amplitude cancellation in the simulated surface electromyogram (EMG) and the consequences for spike-triggered averages of motor unit potentials derived from the interference and rectified EMG signals. The surface EMG was simulated from prescribed recruitment and rate coding characteristics of a motor ...

In this letter we comment on partial parallel interference cancellation as discussed in the above paper by Divsalar et al. The aforementioned work showed that by multiplying symbol estimates by a factor less than unity in early stages of cancellation, the performance of parallel cancellation can be improved relative to full (“brute force”) cancellation. In this letter we analyze the improvement...

In real propagation environment, channel reuse causes co-channel interference which will degrade MIMO channel performance. A Successive Interference Cancellation (SIC) detection algorithm with 64-QAM technique is used to improve the quality of received signal in a high interference environment. Using Concatenating MMSE with SIC equalization, better cancellation gain can be achieved. In this pap...

A large number of the existing and planned 3G networks rely on the 3GPP WCDMA standard. Since the downlink of WCDMA systems is usually interference limited, interference cancellation algorithms that reduce the interference on the desired signal can significantly improve the system capacity. In this paper, the system-level performance gain that can be achieved by interference cancellation on the...

Efficient interference cancellation often requires nonlinear processing of a reference signal. In this paper, hyper radial basis function (HRBF) neural networks for adaptive interference cancellation is developed. We show that the HRBF networks, with an appropriate learning algorithm, is able to approximate the interference signal more efficiently than standard radial basis function (RBF) netwo...

Multi-Input Multi-Output (MIMO) Multiple Access Channels (MAC) for two-user suffers from co-channel interference. For this problem, an interference cancellation scheme based on limited feedback is proposed. Through diagonalization processing for transmitted signals according to feedback information, the cochannel interference is eliminated. Not only the reliability is improved, but also each si...

Multiple connected devices sharing common wireless resources might create interference if they access the channel simultaneously. Medium access control (MAC) protocols generally regulate the access of the devices to the shared channel to limit signal interference. In particular, irregular repetition slotted ALOHA (IRSA) techniques can achieve high-throughput performance when interference cancel...
