Efficient VLSI implementation of soft-input soft-output fixed-complexity sphere decoder
Fixed-complexity sphere decoder (FSD) is one of the most promising techniques for the implementation of multiple-input multiple-output (MIMO) detection, with relevant advantages in terms of constant throughput and high flexibility of parallel architecture. The reported works on FSD are mainly based on software level simulations and a few details have been provided on hardware implementation. In...
متن کاملVLSI Implementation for Interpolation-based Matrix Inversion for MIMO-OFDM Receivers
Matrix inversion block is one of the computationally intensive blocks in communications system. To reduce the size of hardware implementation is a challenging problem. In MIMO-OFDM system, the receiver which uses zero-forcing (ZF) or minimum mean square error (MMSE) scheme should calculate the inverse matrices of all sub-carriers. This paper proposes VLSI architecture for interpolation-based ma...
متن کاملEnabling VLSI Processing Blocks for MIMO-OFDM Communications
Multi-input multi-output (MIMO) systems combined with orthogonal frequency-division multiplexing (OFDM) gained a wide popularity in wireless applications due to the potential of providing increased channel capacity and robustness against multipath fading channels. However these advantages come at the cost of a very high processing complexity and the efficient implementation of MIMO-OFDM receive...
متن کاملA Parallel MCMC-Based MIMO Detector: VLSI Design and Algorithm
Stochastic detection for multi-antenna (MIMO) systems promises communications performance close to max-log detection for certain SNR regimes, especially when the system iterates between detector and channel decoder following the Turbo Principle. In this work, we propose a parallel VLSI architecture for soft-input soft-output Markov chain Monte Carlo based stochastic MIMO detection. It features ...
متن کاملVLSI Implementation of a Fixed-Complexity Soft-Output MIMO Detector for High-Speed Wireless
This paper presents a low-complexity MIMO symbol detector with close-Maximum a posteriori performance for the emerging multiantenna enhanced high-speed wireless communications. The VLSI implementation is based on a novel MIMO detection algorithm called Modified Fixed-Complexity Soft-Output (MFCSO) detection, which achieves a good trade-off between performance and implementation cost compared to...
