Analysis and Design of Carrier-Recovery Loop

In modern communication,it is often need to recover carrier and demodulate signal promptly and precisely. This paper implements carrier recovery by using a typical inverse modulated loop of base-band-modulated regeneration and analyzes the basic principle of the loop. In according to the specification of the loop,the design of the loop and main parameters are given in the paper.
