On Gaussian MIMO compound wiretap channels
— We study the two-user one-eavesdropper discrete memoryless compound wiretap channel, where the transmitter sends a common confidential message to both users, which needs to be...

Diversity-Multiplexing Tradeoff in Selective-Fading Multiple-Access MIMO Channels
We establish the optimal diversity-multiplexing (DM) tradeoff of coherent selective-fading multiple-access multiple-input multiple-output (MIMO) channels and provide corresponding ...

Diversity Analysis of coded SVD Schemes for MIMO Spatial Multiplexing Systems
— When channel state information (CSI) is available at both transmit and receive sides, singular value decomposition (SVD) converts the MIMO channel into parallel subchannels. It...

Closed-Form Exact BER and Optimization of Generalized Orthogonal STBCs
Abstract--The closed-form exact bit error rate (BER) expressions of generalized orthogonal space-time block codes (OSTBCs) are first derived for quadrature amplitude modulation (QA...

The Effect of Ordered Detection and Antenna Selection on Diversity Gain of Decision Feedback Detector
— The decision feedback detector (DFD) can achieve the high spectral efficiency of a MIMO channel in that it converts the MIMO channel into multiple parallel layers, through whi...
