Description of the invention (1) Technical field of the invention The present invention relates to a method and device for a transceiver architecture for radio communication, and more particularly to a method for integrating multiple radio frequency modes into a unified transceiver architecture and its method. Architecture. '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. Direct sequence and frequency hopping are two methods widely used in spread spectrum communication. For example, the wireless local area network (WUN) uses direct sequence spread spectrum, and the Bluetooth system (B 1 uet ο 〇th) uses frequency hopping spread spectrum. 0 Limited by insufficient frequency resources. 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. In particular, a method and a system are needed, which can be installed on a single device equipped with a single RF module, and support both WLAN and Blue tooth systems.

Because different multi-mode communication is used for the transmission connection, the frequency channel rate will be switched, so the area with the shortest area can be achieved by reducing the lock width if possible.

Adjustment analysis ivi ty) I Stabilization time = When the system is operating, the cut-off frequency adjustment of adjustable bandwidth low pass 32 and 33 is between 55 () The frequency hopping rate from 1 ^ to π㈣z,-the fastest and adjustable frequency hopping rate is taken as: transmission characteristics, f data packets are in-the frequency channel that the specific transmission month owes to the special frequency, randomly in the frequency band. Because the stabilization time of the regional oscillator is determined by one hop, the stabilization time of the oscillator is to choose 22ms of Bluetooth in the multi-mode communication system. This stabilization time is improved, and the frequency of an adjustable bandwidth loop filter 22 of phase loop 21 can reduce phase noise and improve "" The effect of system adjustment is to programmatically set the phase-locked loop 2 division § This register is used to obtain the frequency by the ratio of the two registers. The form of the programmable register is transmitted to the register via the I 2 C cable. The control mechanism is used to maintain the signal strength of the I channel and the Q channel before the digital converter. The maximum adjustment dynamics of the automatic gain control at the receiving end must meet the minimum sensitivity of the multi-mode communication system. For FHSS and TDMA systems, the receiving The terminal should choose a minimum time to avoid automatic level control before the packet.
