ASIC Implementation of Soft-Input Soft-Output MIMO Detection Using MMSE Parallel Interference Cancellation
TLDR
We propose a low-complexity soft-input soft-output (SISO) minimum mean-square error (MMSE) based parallel interference cancellation algorithm, develop a suitable VLSI architecture, and present a corresponding four-stream 1.5 mm2 detector chip in 90 nm CMOS technology. Expand

Low-Complexity MIMO Data Detection using Seysen's Lattice Reduction Algorithm
TLDR
We propose and develop the application of Seysen's algorithm (SA) to LR-assisted MIMO detection, and we show that the SA is a promising alternative to the LLL algorithm. Expand

Efficient detection algorithms for MIMO channels: a geometrical approach to approximate ML detection
TLDR
It is well known that suboptimal detection schemes for multiple-input multiple-output (MIMO) spatial multiplexing systems (equalization-based schemes as well as nulling-and-cancelling schemes) are unable to exploit all of the available diversity, and thus, their performance is inferior to ML detection.
