Reduced complexity detection in MIMO systems with SC-FDE modulations and iterat...
Ribeiro, Filipe Casal; Guerreiro, João; Dinis, Rui; Cercas, Francisco; Silva, AdãoThis paper considers a Multiple-Input Multiple-Output (MIMO) system with P transmitting and R receiving antennas and different overall noise characteristics on the different receiver antennas (e.g., due to nonlinear effects at the receiver side). Each communication link employs a Single-Carrier with Frequency-Domain Equalization (SC-FDE) modulation scheme, and the receiver is based on robust iterative frequency...
Robust receivers for base station cooperation systems
Dinis, Rui; Ribeiro, Filipe Casal; Guerreiro, João; Cercas, Francisco; Silva, Adãon BS (Base Station) cooperation architectures the MTs (Mobile Terminals) in adjacent cells can operate in the same frequency, with the signal's separation and/or MTs detection being performed by a CPU (Central Processing Unit). This results in a substantial improvement in the overall system's capacity and spectral efficiency when compared to conventional cellular systems. To decrease the data load in the backha...
Analytical BER Performance Evaluation in SISO and MIMO Environments with SC-FDE...
Dinis, Rui; Ribeiro, Filipe Casal; Cercas, Francisco; Silva, AdãoThis paper presents the analysis of the obtainment of the theoretical bit error rate (BER) performance in single-input–single-output and multiple-input–multiple-output systems with single-carrier with frequency-domain equalization modulations and iterative receivers based on the iterative block decision feedback equalization concept. Through the consideration of a Gaussian-based approach to obtain the BER perfo...
Multiuser detection for the uplink of clustered 5G systems with universal frequ...
Dinis, Rui; Ribeiro, Filipe Casal; Cercas, Francisco; Silva, AdãoWith 5G (Fifth generation) cellular communications, systems have to be able to cope with a massive increase of mobile devices and services and simultaneously improve the system’s spectral efficiency, as well as dealing with high interference levels. Base Station (BS) cooperation architectures jointly with block transmission techniques, such as OFDM (Orthogonal Frequency Division Multiplexing) for the downlink a...

Dinis, Rui; Ribeiro, Filipe Casal; Cercas, Francisco; Silva, AdãoThe presented paper considers the uplink transmission in base station (BS) cooperation schemes where mobile terminals (MTs) in adjacent cells share the same physical channel. We consider single-carrier with frequency-domain equalization (SC-FDE) combined with iterative frequency-domain receivers based on the iterative block decision feedback equalization (IB-DFE). We study the quantization requirements when sen...
