2、2.11n WLAN RADIO FREQUENCY TRANSCEIVER SYSTEM LEVEL MODULING AND SIMULATION ABSTRACT ABSTRACT While computers and communication technology are exploding, Wireless Local Area Networks are prevailing increasingly in pers

3、onal and commercial computer field. WLAN are evolving toward using higher frequencies, wider bandwidth and more functionality to satisfy growing demands of users worldwide. IEEE802.11a/b/g is one of best wireless protoco

4、l standard, but it doesn’t meet the need of wireless growing communication. IEEE802.11n standard is the new substitute of 802.11g. It works in the higher transport speed, more covered area, is compatible to 802.11a/b/g.

5、With higher operation frequency and more complex protocol, RF front end design isn’t independent from digital base band. Tools of accessorial computer analysis and synthesis couldn’t meet co-simulation of digital and RF.

6、 So we need develop modeling and simulation of RF circuit’s system level design. In this paper we use Matlab/Simulink to modeling and simulating RF front end circuit base on 802.11n and establish environment of digital a

7、nd RF co-simulation. In this paper the main work is done as following: First, the standard of WLAN is introduced, and the general RF circuit design theories and methods are discussed. Then, we discuss the key points on R

8、F system design and simulate separately link budget calculation of the transceiver RF system, getting circuit system in accord with the standard. Last, we model building block and simulate the whole system including digi
