Performance of MIMO With Cyclic Coded OSTBC Using OFDM
Wireless designers constantly seek to improve the spectrum efficiency/capacity, coverage of wireless networks, and link reliability. Space-time wireless technology that uses multiple antennas along with appropriate signalling and receiver techniques offers a powerful tool for improving wireless performance Space-time block codes were designed to achieve the maximum diversity order for the given number of transmit and receive antennas subject to the constraint of having a simple linear decoding algorithm. This has made space-time block codes a very poplar scheme and most widely used. In this paper, the authors discuss coded modulation schemes designed for multiple antennas wireless channels without information of the channel at the transmitter.
