Rotation Invariant Subcarrier Mapping over DVB-T2 Reserved Tones

This paper presents a new approach, named Rotation Invariant Subcarrier Mapping (RISM), to Peak-to-Average-Power-Ratio (PAPR) reduction in OFDM systems. This technique enables data transmission over those subcarrier which are dedicated to the PAPR reductio ...

Approximate Capacity of the Dirty Multiple-Access Channel With Partial State Information at the Encoders

I-Hsiang Wang

In this paper, we consider the K-user Gaussian multiple-access channel with multiple independent additive white Gaussian interferences. Each interference is known to exactly one transmitter non-causally. The capacity region is characterized to within a bou ...

Extracting Mobile Behavioral Patterns with the Distant N-Gram Topic Model

Daniel Gatica-Perez, Katayoun Farrahi

Mining patterns of human behavior from large-scale mobile phone data has potential to understand certain phenomena in society. The study of such human-centric massive datasets requires new mathematical models. In this paper, we propose a probabilistic topi ...

Channel Coding Optimization Based on Slice Visibility for Transmission of Compressed Video over OFDM Channels

Laura Toni

Optimization of multimedia transmissions over wireless channels should be aimed at maximizing the video quality perceived by the final user. For transmission of video sequences over an orthogonal frequency division multiplexing (OFDM) system in a slowly va ...

Reconfigurable parasitic antennas for compact mobile terminals in multiuser wireless systems

Julien Perruisseau-Carrier

This article considers the exploitation of parasitic antenna arrays in multi-user (MU) wireless communication systems by using their adaptive beamforming capabilities in order to improve the average system throughput. The use of parasitic arrays and especi ...

Implementation and Optimization of a Galileo E1 Two-Step Tracking Algorithm using Data/Pilot Combining and Extended Integration Time

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic, Youssef Tawk

This paper brings additional light on the previously proposed two-step tracking algorithm for E1 CBOC tracking. More specifically, assessment of the different DLL and PLL tracking loop architectures are analyzed, taking into consideration coherent and non- ...

Integer-Forcing Linear Receivers: A New Low-Complexity MIMO Architecture

Michael Christoph Gastpar

We propose a new framework for MIMO decoding based on a recently developed technique for reliably conveying linear equations over wireless channels. Each transmit antenna sends an independent data stream using the same linear code. As a result, any integer ...

A real-time 4-stream MIMO-OFDM transceiver: System design, FPGA implementation, and characterization

Andreas Peter Burg

When designing complex communication systems, such as MIMO-OFDM transceivers, prototypes have become an important tool for understanding the implementation trade-offs and the system behavior. This paper presents a real-time FPGA prototype for a 4-stream MI ...

Smart Antenna-Aided Multicarrier Transceivers for Mobile Communications

Yosef Akhtman

In spite of an immense interest from both the academic and the industrial communities, a practical multipleinput multiple-output (MIMO) transceiver architecture, capable of approaching channel capacity boundaries in realistic channel conditions remains lar ...

Joint compensation of transmitter and receiver impairments in OFDM systems

Ali H. Sayed

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 ...
