Study of Multiuser Multiple-Antenna Wireless Communications Systems Based on Super-Resolution Arrays
S. Pinto, R. C. de Lamare
This work studies multiple-antenna wireless communication systems based on super-resolution arrays (SRAs). We consider the uplink of a multiple-antenna system in which users commun…
Study of Block Diagonalization Precoding and Power Allocation for Multiple-Antenna Systems with Coarsely Quantized Signals
S. Pinto, R. de Lamare
In this work, we present block diagonalization and power allocation algorithms for large-scale multiple-antenna systems with coarsely quantized signals. In particular, we develop C…
Study of Coarse Quantization-Aware Block Diagonalization Algorithms for MIMO Systems with Low Resolution
S. B. Pinto, R. C. de Lamare
It is known that the estimated energy consumption of digital-to analog converters (DACs) is around 30\% of the energy consumed by analog-to-digital converters (ADCs) keeping fixed…
Direction Finding Based on Multi-Step Knowledge-Aided Iterative Conjugate Gradient Algorithms
S. Pinto, R. C. de Lamare
In this work, we present direction-of-arrival (DoA) estimation algorithms based on the Krylov subspace that effectively exploit prior knowledge of the signals that impinge on a sen…
Study of Multi-Step Knowledge-Aided Iterative Nested MUSIC for Direction Finding
S. Pinto, R. C. de Lamare
In this work, we propose a subspace-based algorithm for direction-of-arrival (DOA) estimation applied to the signals impinging on a two-level nested array, referred to as multi-ste…
Multi-Step Knowledge-Aided Iterative ESPRIT for Direction Finding
S. F. B. Pinto, R. C. de Lamare
In this work, we propose a subspace-based algorithm for DOA estimation which iteratively reduces the disturbance factors of the estimated data covariance matrix and incorporates pr…
