An Enhanced Access Reservation Protocol with a Partial Preamble Transmission Mechanism in NB-IoT Systems
Taehoon Kim, Dong Min Kim, Nuno Pratas +2
In this letter, we propose an enhanced Access Reservation Protocol (ARP) with a partial preamble transmission (PPT) mechanism for the narrow band Internet of Things (NB-IoT) system…
New binary and ternary LCD codes
Carlos Galindo, Olav Geil, Fernando Hernando +1
LCD codes are linear codes with important cryptographic applications. Recently, a method has been presented to transform any linear code into an LCD code with the same parameters w…
Cramér-Rao Bounds for Blind Multichannel Estimation
Elisabeth de Carvalho, Dirk Slock
In some estimation problems, not all the parameters can be identified, which results in singularity of the Fisher Information Matrix (FIM). The Cramér-Rao Bound (CRB), which is the…
Modelling of Path Arrival Rate for In-Room Radio Channels with Directive Antennas
Troels Pedersen
We analyze the path arrival rate for an inroom radio channel with directive antennas. The impulse response of this channel exhibits a transition from early separate components foll…
Compressive Coded Random Access for Massive MTC Traffic in 5G Systems
Gerhard Wunder, Cedomir Stefanovic, Petar Popovski +1
Massive MTC support is an important future market segment, but not yet efficiently supported in cellular systems. In this paper we follow-up on recent concepts combining advanced M…
A Pseudo-Bayesian Approach to Sign-Compute-Resolve Slotted ALOHA
Jasper Goseling, Cedomir Stefanovic, Petar Popovski
Access reservation based on slotted ALOHA is commonly used in wireless cellular access. In this paper we investigate its enhancement based on the use of physical-layer network codi…
User Activity Detection in Massive Random Access: Compressed Sensing vs. Coded Slotted ALOHA
Veljko Boljanovic, Dejan Vukobratovic, Petar Popovski +1
Machine-type communication services in mobile cel- lular systems are currently evolving with an aim to efficiently address a massive-scale user access to the system. One of the key…
On affine variety codes from the Klein quartic
Olav Geil, Ferruh Ôzbudak
We study a family of primary affine variety codes defined from the Klein quartic. The duals of these codes have previously been treated in [12, Ex. 3.2]. Among the codes that we co…
Wireless Channel Modeling Perspectives for Ultra-Reliable Low Latency Communications
Patrick C. F. Eggers, Marko Angjelichinoski, Petar Popovski
Ultra-Reliable Low Latency Communication (URLLC) is one of the distinctive features of the upcoming 5G wireless communication, going down to packet error rates (PER) of .…
Statistical Multiplexing of Computations in C-RAN with Tradeoffs in Latency and Energy
Anders E. Kalør, Mauricio I. Agurto, Nuno K. Pratas +2
In the Cloud Radio Access Network (C-RAN) architecture, the baseband signals from multiple remote radio heads are processed in a centralized baseband unit (BBU) pool. This architec…
Revisiting Frequency Reuse towards Supporting Ultra-Reliable Ubiquitous-Rate Communication
Jihong Park, Dong Min Kim, Petar Popovski +1
One of the goals of 5G wireless systems stated by the NGMN alliance is to provide moderate rates (50+ Mbps) everywhere and with very high reliability. We term this service Ultra-Re…
On squares of cyclic codes
Ignacio Cascudo
The square of a linear error correcting code is the linear code spanned by the component-wise products of every pair of (non-necessarily distinct) words in . Square…
An Upper Bound to Zero-Delay Rate Distortion via Kalman Filtering for Vector Gaussian Sources
Photios A. Stavrou, Jan Ostergaard, Charalambos D. Charalambous +1
We deal with zero-delay source coding of a vector Gaussian autoregressive (AR) source subject to an average mean squared error (MSE) fidelity criterion. Toward this end, we conside…
Delivery Latency Trade-Offs of Heterogeneous Contents in Fog Radio Access Networks
Jasper Goseling, Osvaldo Simeone, Petar Popovski
A Fog Radio Access Network (F-RAN) is a cellular wireless system that enables content delivery via the caching of popular content at edge nodes (ENs) and cloud processing. The exis…
