Emerging demands for high data rate services and high spectral efficiency are the key driving forces for the continued technology evolution in wireless communications. MIMO (Multiple Input and Multiple Output) technology has attracted attention in wireless communications, because it offers significant increases in data throughput and link range without additional bandwidth or transmit power. It achieves this by higher spectral efficiency (more bits per second per hertz of bandwidth) and link reliability or diversity (reduced fading). Orthogonal Space-Time Block Codes (STBC's) have received considerable attention in recent open-loop Multiple-Input-Multiple-Output (MIMO) wireless communication because they allow low decoding complexity and guarantee full diversity.
