Fifth-generation (5G) cellular communication systems have embraced massive multiple-input-multiple-output (MIMO) in the low- and mid-band frequencies. In a multiband system, the base station can serve different users in each band, while the user equipment can operate only in a single band simultaneously. This paper considers a massive MIMO system w...
Preprint
The increasing complexity of configuring cellular networks suggests that machine learning (ML) can effectively improve 5G technologies. Deep learning has proven successful in ML tasks such as speech processing and computational vision, with a performance that scales with the amount of available data. The lack of large datasets inhibits the flourish...

The fifth-generation (5G) cellular networks incorporate a large variety of technologies in order to address very distinct use cases. Assessing these technologies and investigating future alternatives is complicated when one relies only on simulators. 5G testbeds are an important alternative to simulators and many have been recently described, empha...

5G networks will provide the platform for deploying large number of tenant-associated management, control and end-user applications having different resource requirements at the infrastructure level.In this context, the 5G infrastructure provider must optimize the infrastructure resource utilization and increase its revenue by intelligently admitti...

Article
Information-centric networking (ICN) is one of the most promising research topics for the future Internet. ICN aims at circumventing several issues of current Internet protocol (IP) solutions such as efficient multimedia distribution. Given the huge growth rate of video transmission over mobile networks, it is sensible to consider how 4G/5G network...

Quality of Service (QoS) constraints are crucial in 5G networks. The paper presents a provisioning strategy for connectivity services with different priorities based on reinforcement learning able to accommodate QoS requirements while maximizing provider profits.
Conference Paper
Full-text available
There are several commercial text-to-speech (TTS) systems that generate speech signals that sound very natural. A distinct problem is utterance copy, which consists in taking speech as input (instead of text, as in TTS) and find the input parameters that would drive a speech synthesizer to generate speech that mimics the target speech with respect...
Conference Paper
Full-text available
Advances in speech processing research rely on the availabil-ity of public resources such as corpora, statistical models and baseline systems. In contrast to languages such as English, there are few specific resources for Brazilian Portuguese. This work describes efforts aiming to decrease such gap. Baseline acoustic models for Brazilian Portuguese...

Conference Paper
Full-text available
This work is part of the effort to develop a speech recognition system for Brazilian Portuguese. The resources for the training and test stages of this system, such as corpora, pronunciation dictionary, language and acoustic models, are publicly available. Here, an application programming interface is proposed in order to facilitate using the open-...
Article
Full-text available
An automatic speech recognition system has modules that depend on the language and, while there are many public resources for some languages (e.g., English and Japanese), the resources for Brazilian Portuguese (BP) are still limited. This work describes the development of resources and free tools for BP speech recognition, consisting of an applicat...

1 A Interface de Programação Ao promover o amplo desenvolvimento de aplicações baseadas em reconheci-mento de voz, os autores observaram que não era suficiente apenas tornar os recursos disponíveis, tais como modelos de linguagem. Esses recursos sãó uteis para pesquisadores, mas o que a maioria dos programadores deseja e a prati-cidade oriunda de u...
