Space-Time Block Codes
Space-time block codes are coding and modulation schemes for multi-input multi-output wireless communication systems which map information bits into multidimensional signals to be transmitted by multiple transmit antennas.
In the 1990s, a revolutionary theoretical work revealed that multi-input multi-output (MIMO) wireless communications can provide substantial capacity increase in rich scattering and reflection environments compared to conventional single-input single-output (SISO) systems (Telatar, 1995; Foschini and Gans, 1998). Then, performance analysis for MIMO systems with practical signal transmissions and receiver detection/decoding was carried out in Guey et al. (1999), Tarokh et al. (1998) in which two design criteria (one related to coding gain and one related to diversity order or degree of redundancy) were proposed for space-time (ST) signal/code designs in order to...
