A robust LU polynomial matrix decomposition for spatial multiplexing
EURASIP Journal on Advances in Signal Processing, 2020 This paper considers time-domain spatial multiplexing in MIMO wideband system, using an LU-based polynomial matrix decomposition. Because the corresponding pre- and post-filters are not paraunitary, the noise output power is amplified and the performance
