Abstract: A switching method for multiple antenna arrays is disclosed which including: turning on a number of antenna arrays of an electronic device, and obtaining multiple received powers of a beam signal; turning off the antenna array(s) other than the antenna array having the largest received power, and calculating multiple first power ratio parameters according to the received powers; calculating a first channel information of the antenna array which is turned on; calculating a first virtual channel information of each of the antenna arrays which are turned off according to the first channel information, the first power ratio parameter corresponding to each of the antenna arrays which are turned off and an angle mapping table; and selecting one of the antenna arrays to turn on according to the first channel information and all the first virtual channel information, and turning off the rest antenna array(s).

Abstract: A communication system and a codec method based on deep learning and known channel state information (CSI) are provided. The communication system includes: a first electronic apparatus including a known first link CSI and a CSI encoder having a deep learning function; and a second electronic apparatus including a known second link CSI and a CSI decoder having a deep learning function. The first and second link CSIs have a correlation or a similarity. The CSI encoder of the first electronic apparatus encodes or compresses the first link CSI into the first codeword, and feeds the first codeword back to the second electronic apparatus via a feedback link. The CSI decoder of the second electronic apparatus encodes or compresses the second link CSI into a second codeword, and decodes or restores the first link CSI of the first electronic apparatus based on the first codeword and the second codeword.
