In space-time, space-frequency, or space-time-frequency codes where the orthogonal property and the ability to be preserved through the propagation channel is a key factor in the total system performance. Performance evaluation of space-time block code with constellation rearrangement orthogonal transmitter diversity such as time diversity and frequency diversity is quite simple to implement and, with optimum signal combining, can take full advantage of fading multipath channels receive diversity techniques.

Iiiorthogonal space-time block codes (ostbcs) space–time block coding is a technique used to improve the performance of a wireless transmission system, where the receiver is provided with multiple signals carrying the same information. In this paper, we consider the performance evaluation of space time block code (stbc)) with coordinate interleaved orthogonal design (ciod) over time selective channel in case of quasi static channel, stbc-ciod satisfies full rate and full diversity (frfd) property with the single symbol decoding. Orthogonal space–time block coding (ostbc) is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data-transfer.
