A MIMO channel perturbation analysis for robust bit loading
In narrowband multiple-input multiple-output (MIMO) communication systems, when the channel state information (CSI) is known perfectly at the transmitter and the receiver, techniq...

On the secrecy capacity of frequency-selective fading channels : A practical vandermonde precoding
We study the secrecy capacity of the frequency-selective wiretap channel. Assuming that a guard interval of L symbols is inserted to avoid the inter-block interference and these s...

Sphere Decoder for a MIMO Multi-User MC-CDMA Uplink in Time-Varying Channels
— We focus on iterative detection for the uplink of a multi-carrier (MC) code division multiple access (CDMA) system based on orthogonal frequency division multiplexing (OFDM). T...

MIMO Gaussian channels with arbitrary inputs: optimal precoding and power allocation
We investigate the linear precoding and power allocation policies that maximize the mutual information for general multiple-input multiple-output (MIMO) Gaussian channels with arb...
