Abstract
In today’s communication technology, wireless local area network (Wireless LAN) and Bluetooth are two most used standards in the wireless communication network. Because the requirement and application of the two systems are different and irreplaceable, both of two sysyems are widely used in variety of electronic device. However, Wireless LAN and Bluetooth both utilize 2.4 GHz ISM band, mutual interference occurs while the two systems modulate signals to the same spectrum at the same time, and this will cause transmission error. This is so-called the ISM coexistence issue. According to the idea of joint deteion, the thesis propursed a “Joint Detector” structure, this can solve most situation of the Wireless LAN and Blutooth interfefence, and serve a better transmission service and quality. This structure includes algorithm, CSI estimation under interference. For example, like Bluetooth signal amplitude, phase, Wireless LAN symbol boundary, channel, etc. In the final this research would verify the simulation result of Joint detector.
