Study of Puncturing Techniques for Polar Codes in 5G Cellular and IoT Networks
R. M. Oliveira, R. C. de Lamare
This paper presents a puncturing technique based on the channel polarization index for the design of rate-compatible polar codes in the fifth generation (5G) of wireless systems. T…
Study of Joint Automatic Gain Control and MMSE Receiver Design Techniques for Quantized Multiuser Multiple-Antenna Systems
T. Cunha, R. C. de Lamare
This paper presents the development of a joint optimization of an automatic gain control (AGC) algorithm and a linear \textit{minimum mean square error} (MMSE) receiver for multi-u…
Knowledge-Aided Normalized Iterative Hard Thresholding Algorithms and Applications to Sparse Reconstruction
R. C. de Lamare
This paper deals with the problem of sparse recovery often found in compressive sensing applications exploiting a priori knowledge. In particular, we present a knowledge-aided norm…
Study of Polarization-Driven Shortening for Polar Codes Designed with the Gaussian Approximation
R. M. Oliveira, R. C. de Lamare
This paper presents a polarization-driven (PD) shortening technique for the design of rate-compatible polar codes. The proposed shortening strategy consists of reducing the generat…
Tomlinson-Harashima Precoded Rate-Splitting for Multiuser MIMO Systems
A. Flores, B. Clerckx, R. C. de Lamare
In this work, we investigate the performance of Rate-Splitting (RS) based on Tomlinson-Harashima Precoding (THP) in a multiple-antenna broadcast channel with perfect and imperfect…
Study of Switched Max-Link Buffer-Aided Relay Selection for Cooperative MIMO Systems
F. L. Duarte, R. C. de Lamare
In this paper, we investigate relay selection for cooperative multiple-antenna systems that are equipped with buffers, which increase the reliability of wireless links. In particul…
