Vehicular communications have received a lot of attention in recent years due to the demand for applications to improve safety and travel comfort. Nowadays, IEEE 802.11p seems to be the best positioned standard for providing safety services. However, for non-safety services, which usually do not present tight time restrictions but require high data transfer(More)
Recently, analog joint source-channel coding has been proposed as a means of achieving near-optimum performance for high data rates with a very low complexity. However, no experimental evaluation showing the practical feasibility of this scheme has been performed to date. In this paper, we describe a software-defined radio implementation of an analog joint(More)
The Internet of Things (IoT) is undeniably transforming the way that organizations communicate and organize everyday businesses and industrial procedures. Its adoption has proven well suited for sectors that manage a large number of assets and coordinate complex and distributed processes. This survey analyzes the great potential for applying IoT(More)
Recently, the use of analog joint source-channel coding for the transmission of data samples at high rates has been proposed in the literature. Simulation results have shown that when using this analog scheme over AWGN channels, its performance is close to the theoretical capacity limits for several source distributions and transmission rates. In this paper(More)
We analyze Multiple-Input Multiple-Output (MIMO) coded modulation systems where either Bit-Interleaved Coded Modulation (BICM) with spatial multiplexing or concatenation of channel coding and Space-Time Block Codes (STBCs) is used at transmission, assuming iterative Turbo-like decoding at reception. We optimize SeriallyConcatenated Low-Density Generator(More)
Sir: T-cell lymphomas with a follicular growth pattern (FTCLs) are a rare and otherwise unspecified variant of peripheral T-cell lymphoma (PTCL-u), since their cellular origin and clinical implications are uncertain. We report a case of follicular T-cell lymphoma with a pure follicular pattern, paratrabecular bone marrow infiltration and a T(More)
We investigate the ability of Serially-Concatenated Low Density Generator Matrix (SCLDGM) codes to approach the capacity of ergodic Multiple-Input Multiple-Output (MIMO) channels. First, we explain how to design good SCLDGM codes using EXtrinsic Information Transfer (EXIT) analysis and optimum detection. However, optimum detection becomes unfeasible in many(More)
We propose a distributed multilayer architecture that provides user access to a MIMO testbed at the convenient abstraction level for researchers. This novel architecture releases the user from the need of low-level programming, making the MIMO testbed accessible through high level software (i.e. Matlab or similar). The layers of this architecture are highly(More)
