Abstract (Summary)

Space-time codes are a standout amongst the most prominent procedure utilized as a part of the multiple-input multiple-output (MIMO) systems in the advanced communication systems. While ordinary transmission between one transmit and one receive antenna is utilized, one can see neither diversity gain nor coding gain, which eventually implies that a critical change in the transmission cannot be observed. Space-time codes can be effectively connected through multiple transmit antennas and optional number of receive antennas. There are several approaches to provide diversity gain. The researches which are developed to achieve diversity gain by late 1990's are called as space-time block codes (STBC). Despite the fact that the STBC is anything but easy to execute, they do not provide any coding gain. Subsequently, so as to accomplish the coding gain other than the diversity gain, the space-time trellis codes (STTC) are connected all through this theory. STTC, which gives coding gain in regards to the number of the states, is then joined with the orthogonal frequency division multiplexing (OFDM) systems, which is a prominent transmission method to send orthogonal signals with no interference between the subcarriers. It is ultimately called as STTC-OFDM systems.
