Transmit Diversity for DS-CDMA/MMSE-FDE with Frequency-Domain ICI Cancellation
—Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can provide a better bit error rate (BER) performance than rake combining. However, t...

Design of Collaborative Codes Achieving Space-Time Diversity
— In wireless networks, the use of collaboration has been shown to provide an increase in reliability due to an increase in diversity. Specifically it has been shown that by havi...

On the ergodic sum-rate performance of CDD in multi-user systems
— The main focus of space-time coding design and analysis for MIMO systems has been so far focused on singleuser systems. For single-user systems, transmit diversity schemes suff...

Existence and construction of noncoherent unitary space-time codes
We consider transmission using transmit and reception using receive antennas in a wireless environment assuming that neither the transmitter nor the receiver knows the channel coef...

Low complexity virtual antenna arrays using cooperative relay selection
We study the diversity-multiplexing tradeoff in cooperative diversity systems involving multiple relays. We focus on low complexity architectures that do not require simultaneous...
