Wireless communication faces many challenges such as limited available wireless spectrum resources and complex space–time variation in the wireless communication environment. How to effectively utilize the optimal spatial signal combination method to improve the performance and spectrum efficiency of wireless communication systems is a very important and difficult technology for the next generation of wireless communication. This chapter will first introduce the basic theories of multi-antenna spatial signal combination and detection and then introduce the basic knowledge of array antenna from the perspective of signal space propagation. The pattern synthesis technology in the array antenna will be the focus of discussion. Finally, another wide application of multi-antenna technology will be introduced, namely the basic principle and signal detection method of multi-input and multi-output (MIMO) systems.
