Due to the severe conditions of wireless channels, it is crucial for wireless systems to
accommodate some sort of diversity to achieve reliable communication. Different types of …

We introduce a scheme that achieves a diversity gain for coded systems under static fading
conditions by using multiple antennas and random signal mapping. In a two-antenna …

Cyclic delay diversity is a simple, yet effective, transmit diversity scheme for multicarrier

A problem with transmitting correlated symbols over multiple transmit channel paths is that
there is no diversity gain achieved at the receiver. Precoding technique provides a smart …
