'Ϋ Previous technology Spread spectrum communication is an important technology in the field of wireless communication and is widely used because it can resist interference, jamming of signals, and background noise.

One of the shortcomings of wireless communication is the multiple communication standards Will co-existence in the same frequency band (for example: WLAN and Bluetooth in the 2.4Ghz ISM band). Although WLAN and Bluetooth are unique in their respective designs, the lack of a single device that can support both coexistence issues of the two systems will be a major disadvantage. However, the known single device requires multiple RF modules to support the two systems. Figure 1 is a functional architecture diagram showing the architecture of this type of transceiver. The transmitter and transceiver are designed separately. Therefore, multiple sets of RF modules are required, each of which has its own antenna and transmitter / receiver architecture. Therefore, the wireless communication field needs a method and a system to solve this problem.
