Precoding and Spatial Modulation in the Downlink of MU-MIMO Systems
Azucena Duarte, Raimundo Sampaio-Neto
This work focuses on the downlink communication of a multiuser MIMO system where the base station antennas and the users' receiving antennas are all active, but at each transmissio…
Sparsity-Aware Adaptive Algorithms Based on Alternating Optimization with Shrinkage
Rodrigo C. de Lamare, Raimundo Sampaio-Neto
This letter proposes a novel sparsity-aware adaptive filtering scheme and algorithms based on an alternating optimization strategy with shrinkage. The proposed scheme employs a two…
Adaptive Reduced-Rank Processing Using a Projection Operator Based on Joint Iterative Optimization of Adaptive Filters For CDMA Interference Suppression
Rodrigo C. de Lamare, Raimundo Sampaio-Neto
This paper proposes a novel adaptive reduced-rank filtering scheme based on the joint iterative optimization of adaptive filters. The proposed scheme consists of a joint iterative…
Blind Adaptive MIMO Receivers for Space-Time Block-Coded DS-CDMA Systems in Multipath Channels Using the Constant Modulus Criterion
Rodrigo C. de Lamare, Raimundo Sampaio-Neto
We propose blind adaptive multi-input multi-output (MIMO) linear receivers for DS-CDMA systems using multiple transmit antennas and space-time block codes (STBC) in multipath chann…
Reduced-Rank Adaptive Filtering Based on Joint Iterative Optimization of Adaptive Filters
Rodrigo C. de Lamare, Raimundo Sampaio-Neto
This letter proposes a novel adaptive reduced-rank filtering scheme based on joint iterative optimization of adaptive filters. The novel scheme consists of a joint iterative optimi…
Minimum Mean-Squared Error Iterative Successive Parallel Arbitrated Decision Feedback Detectors for DS-CDMA Systems
Rodrigo C. de Lamare, Raimundo Sampaio-Neto
In this paper we propose minimum mean squared error (MMSE) iterative successive parallel arbitrated decision feedback (DF) receivers for direct sequence code division multiple acce…
