Multiple antenna (MIMO) devices are widely used to increase reliability and information bit rate. Optimal error rate performance (full diversity and large coding gain), for unknown channel state information at the transmitter and for maximal rate, ca

or a generic communications link, this example focuses on transmit diversity in lieu of traditional receive diversity. Using the flat-fading Rayleigh channel, it illustrates the concept of Orthogonal Space-Time Block Coding, which is employable when

基于凸优化算法，频率分集阵列天线在全时空域内可控点聚焦，实现对动目标追踪、多目标聚焦，可用于实现点对点秘密通信(Based on convex optimization algorithm, the frequency diversity array antenna can focus on controllable points in the whole time and space domain, and can be used to realize point to point secre
