In the Cloud Radio Access Network (C-RAN) architecture, a Control Unit (CU) implements the baseband processing functionalities of a cluster of Base Stations (BSs), which are connected to it through a fronthaul network. This architecture enables centralized processing at the CU, and hence the implementation of enhanced interference mitigation strategies, but it also entails an increased decoding...

source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

In many signal processing applications, such as EEG analysis, the non-stationary signal is often required to be segmented into small epochs. This is accomplished by drawing the boundaries of signal at time instances where its statistical characteristics, such as amplitude and/or frequency, change. In the proposed method, the original signal is initially decomposed into signals with different fr...

Wireless Sensor Networks (WSNs) provide a new paradigm for sensing and disseminating information from various environments, with the potential to serve many and diverse applications. Current WSNs typically communicate directly with a centralized controller or satellite. On the other hand, a smart WSN consists of a number of sensors spread across a geographical area; each sensor has wireless com...

the range imaging based on conventional pulse compression technique requires lfm signal that sampled by nyquist rate. in order to high resolution increased in range in pulse compression, so the lfm bandwidth has to increase. consequently this procedure dictated limitations on adc sampling. the stretch processing is one of techniques decreasing nyquist rate in radars. in this method the nature o...

In most database systems with production rule facilities, rules respond to operations on centralized data and rule processing is performed in a centralized, sequential fashion. In parallel and distributed database environments, for maximum autonomy it is desirable for rule processing to occur separately at each site (or node), responding to operations on data at that site. However, since rules ...

We propose a decentralized receiver for extra-large multiple-input multiple-output (XL-MIMO) arrays. Our method operates with no central processing unit (CPU) and all the signal detection tasks are done in distributed nodes. exploit combined message-passing framework to design an uncoordinated scheme that overcomes three major challenges XL-MIMO systems: computational complexity, scalability no...
