A family of distributed space-time trellis codes with asynchronous cooperative diversity
—In current cooperative communication schemes, to achieve cooperative diversity, synchronization between terminals is usually assumed, which may not be practical since each termi...

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...

Detecting Malicious Behavior in Cooperative Diversity
—We consider a cooperative diversity scheme where a relay cooperatively enhances communication between a source and destination. In cooperative diversity, due to lack of a mechan...
