Abstract
This paper emphasizes on the characteristics and schemes of carrier acquisition and track in high dynamic and high information-rate situation. Carrier acquisition model is analyzed theoretically and the design princi-ple of carrier acquisition is deduced and described clearly. An algorithm for carrier acquisition in high dy-namic and high information-rate situation is provided. This paper also proves the validity of the algorithm and design scheme in high dynamic and high information-rate situation.

Summary
The HAPS (high altitude platform Station) system has been concentrated on research because of important values in military and application. A combined method of data phase information and carrier frequency estimation was provided in literature [6] by means of correction of the local numerical control oscillator (NCO) through the frequency and phase error estimation. In the literature [7,8] the author analyzed the frequency and phase error by means of the combined method of self-adaptive filter and flatness technology. In order to implement the carrier acquisition and track in high dynamic and high information-rate situation, the technologies referred to the literatures above can’t reach the requirement of the communication system obviously. This paper provides a new and suitable carrier acquisition and track technology for HAPS communication in high dynamic and high information-rate situation and proved its validity
