[hal-01592234] Prototype of a Wireless System for Electrical Impedance Spectroscopy: Demonstration of Real Time Measurements on Cells and Biological Medium

A wireless and portable system, consisting in an electronic board and a computer software graphical interface, is presented as a feasible way to do electrochemical impedance spectroscopy of cells and biological medium. It is designed to work inside a culture chamber performing impedance measurement in the frequency range of 64Hz to 200KHz. [...]

[hal-01590659] Towards Real-Time Polyp Detection in Colonoscopy Videos: Adapting Still Frame-Based Methodologies for Video Sequences Analysis.

Colorectal cancer is the second cause of cancer death in United States: precursor lesions (polyps) detection is key for patient survival. Though colonoscopy is the gold standard screening tool, some polyps are still missed. Several computational systems have been pro- posed but none of them are used in the clinical room mainly due to com- putational constraints. [...]

[hal-01554505] RF transceiver and transmission line behavioral modeling in VHDL-AMS for wired RFNoC

Despite the exceptional progress of MPSoC architectures, on chip communication networks remain a lock for the evolution of their performances due to the power consumption and the delay in data carrying. In this context, the wired radio frequency (RF) network on chip (RFNoC) has emerged. [...]

[tel-01581003] Design process for the optimization of embedded software architectures on to multi-core processors in automotive industry

The recent migration from single-core to multi-core platforms in the automotive domain reveals great challenges for the legacy embedded software design flow. First of all, software designers need new methods to fill the gap between applications description and tasks deployment. [...]

[hal-01586936] Almost universal codes achieving ergodic MIMO capacity within a constant gap

This work addresses the question of achieving capacity with lattice codes in multi-antenna block fading channels when the number of fading blocks tends to infinity. A design criterion based on the normalized minimum determinant is proposed for division algebra multi-block space-time codes over fading channels; this plays a similar role to the Hermite invariant for Gaussian channels. [...]

[cea-01566283] Flexible, Cost-Efficient, High-Throughput Architecture for Layered LDPC Decoders with Fully-Parallel Processing Units

—In this paper, we propose a layered LDPC decoder architecture targeting flexibility, high-throughput, low cost, and efficient use of the hardware resources. The proposed architecture provides full design time flexibility, i.e., it can accommodate any Quasi-Cyclic (QC) LDPC code, and also allows redefining a number of parameters of the QC-LDPC code at the run time. [...]

[cea-01567164] High Throughput FPGA Implementation for regular Non-Surjective Finite Alphabet Iterative Decoders

—This paper deals with the recently introduced class of Non-Surjective Finite Alphabet Iterative Decoders (NS-FAIDs). First, optimization results for an extended class of regular NS-FAIDs are presented. They reveal different possible trade-offs between decoding performance and hardware implementation efficiency. [...]

[hal-01584903] Improving Texture Categorization with Biologically Inspired Filtering

Within the domain of texture classification, a lot of effort has been spent on local descriptors, leading to many powerful algorithms. However, preprocessing techniques have received much less attention despite their important potential for improving the overall classification performance. [...]

[cea-01573431] Code-aware quantizer design for finite-precision min-sum decoders

Classically, the quantization of the soft information supplied to a finite-precision decoder is chosen to optimize a certain criterion which does not depend on the characteristics of the existing code. This work studies code-aware quantizers, for finite-precision min-sum decoders, which optimize the noise threshold of the existing family of Low-Density Parity-Check (LDPC) codes. [...]

[cea-01573437] An Improved SCFlip Decoder for Polar Codes

This paper focuses on the recently introduced Successive Cancellation Flip (SCFlip) decoder of polar codes. Our contribution is twofold. First, we propose the use of an optimized metric to determine the flipping positions within the SCFlip decoder, which improves its ability to find the first error that occurred during the initial SC decoding attempt. [...]
