1. Um estudo sobre a robustez de técnicas de processamento de sinais em sistemas MIMO / A study regarding robustness of signal processing techniques in MIMO systems
Multiple antenna wireless communication systems achieve high data transmission rates and good robustness to channel fading when signals traveling through the system are jointly processed in their transmitters and/ or receivers. In general, signal detection techniques assume perfect knowledge of the channel state information, in both transmitter and receiver,

2. Enumeração de espectro de distâncias de esquemas de modulação codificada em treliça empregando codificação turbo
In this work, a performance analysis of transmission schemes employing turbo trellis coded modulation. In general, the performance analysis of such schemes is guided by evaluating the error probability of these schemes. The exact evaluation of this probability is very complex and inefficient from the computational point of view, a widely used alternative is

4. Performance Analisys of Multicarrier Systems in Peak Clipping Channels / Análise de Desempenho de Sistemas Multiportadora em Canais com Ceifamento de Pico
The advent of Digital Television brought a new scenario to the digital telecommunication systems, presenting new problems and challenges to be efficiently solved. Today, there are three different standards for Digital Television available: the ATSC developed in USA, DVB-T developed in Europe and ISDB-T developed in Japan. Two of these standards use a transmi

5. ANALYSIS OF A RANDOM MULTIPLE ACCESS SYSTEM / ANÁLISE DE UM SISTEMA DE MÚLTIPLO ACESSO ALEATÓRIO
This work is related to random multiple access systems to be used in connection with satellite communication systems. The use of a time-frequency code allows the system to be operated without any Kind of synchronization among users. The symbol error probability associated to any user is obtained, thourgh simulation, as a function of the number of users and t

6. PROBALIDADE DE ERRO NA TRANSMISSÃO BINÁRIA POR UM CANAL COM DESVANECIMENTO SELETIVO DE FREQUÊNCIA / ERROR PROBABILITY IN THE BINARY TRANSMISSION THROUGH A FREQUENCY SELECTIVE CHANNEL
In this work it is shown in detail the necessary steps to compute the erros probability taking into account the intersymbol interference due to the frequency-selective fading in the communication channel. A comparison is made between Bello and Nelin¿s and Bailey and Lindenlaub¿s results for the error probabilities with intersymbol interference due to two a
