Space-time Coding




Space time codes may be split into two main types:

STC may be further subdivided according to whether the receiver knows the Channel impairments. In coherent STC, the receiver knows the channel impairments through training or some other form of estimation. These codes have been studied more widely because they are less complex than their non-coherent counterparts. In noncoherent STC the receiver does not know the channel impairments but knows the statistics of the channel.4}} In Differential Space–time Code s neither the channel nor the statistics of the channel are available.5 }}

  • MIMO Communications — the term for wireless communication systems employing multiple antennas at both a transmitter and a receiver.
