Front-end Design Of The Wireless Receiver And Study Of Multiple Calibration

This paper takes the application background of certain system developed by my work team. Shortwave communication is the foundation of research . Based on the development of technology on modern digital signal processing and FPGA CMOS chips, we emphasizely study the front-end of receiver on structure,performance,system simulation,analog devices and PCB , the technology of synchronization implement on multiple calibration is also implemented.The primary work of my paper is as follows:This page first introduces the theory basis of the design of receiver, analyzes the basic technology of receiver, and gives the structure of reveiver adapted to this paper based on a new design method . Then makes path-budget of the performance parameters with expressions , experience and AppCad. It offers data to next design steps. Based with the data above, it simulates the whole performances with ADS, and analyses the results carefully. Thus, it's completely according to the design requirement.Then analyzes the front-end analog devices including ADC , and studies the requirement of performance on other analog devices, giving out the PCB scheme of important ICs and the receiver. Besides, it discusses the feasibility of programmable analog devices and get the conclusion on theoretical analyse.Finally studies the basic model of multiple calibration algorithm, and analyzes the performance of the methods via simulation before and after calibration. It studies the synchronization problem of multiple calibration algorithm in FPGA Design. After that , the performance of the calibration via simulation could be analyzed.In the end of the paper , I summarize this thesis and give a prospect of the future work.
