The embodiments of the present invention relate to a wireless communication system, comprising a wireless communication array and a wireless signal transceiving chain. The wireless communication array comprises a first array optical fibre, an optical divider and a plurality of wireless communication nodes, wherein the first array optical fibre transmits a first signal optical signal; the optical divider performs division processing on the first signal optical signal to obtain a divided optical signal; and the wireless communication nodes simultaneously and synchronously send first pulse signals. The wireless signal transceiving chain comprises a synchronous controller, a first signal optical fibre, a plurality of first passive optical splitters, a plurality of wireless signal transceiving nodes, a plurality of second passive optical splitters and a second signal optical fibre, wherein the synchronous controller generates a receiving control instruction and sends same to a current wireless signal transceiving node; and the current wireless signal transceiving node generates a first communication optical signal according to a first pulse signal.

The embodiment of the invention relates to a wireless communication method. The method includes the following steps: a first array of optical fibers transmit a first signal optical signal; an opticalsplitter splits the first signal optical signal to obtain multiple paths of identical first branching optical signals; multiple wireless communication nodes synchronously generate the same first pulsesignal, and thus each wireless communication node in a wireless communication array simultaneously and synchronously sends the first pulse signals; a synchronization controller generates a receivingcontrol instruction, and sends the receiving control instruction to a current wireless signal transceiver node through a first signal optical fiber and a first passive optical branching device; the current wireless signal transceiver node receives the first pulse signals simultaneously sent by the multiple wireless communication nodes in the wireless communication array to generate a first communication optical signal; and a second passive optical branching device receives the first communication optical signal sent by the corresponding wireless signal transceiver node and sends the first communication optical signal to a second signal optical fiber.
