As a novel space-based tracking, telemetering and command system, Tracking and Data Relay Satellite System(TDRSS) represents a new direction in the international tracking, telemetering and command field. TDRSS plays an important role in increasing its plus size wedding dresses coverage rate of the mediate/low orbit aircraft and decreasing the amount of ground telemetry stations in the satellite communication system. Therefore, it has a wide application prospect.TDRSS which consists of two geostationary satellites and one land terminal is a TT&C net, it covers blog lace wedding dresses several on-track aircrafts(satellite, spaceship, space station, etc.) and can deliver 300MBPS for the reverse link. As a lot of group delay distortion devices are on the reverse link, such as filters, mixers, power splitters, power amplifiers and so on which will make the high-speed data-transmission wedding gowns dresses signal have group delay distortion and serious signal inter symbol interference, consequentially, the bit error new shoes 2010 rate increases. In this thesis, group delay distortion on the high-speed data signals is focused on, through fundamental research and simulation analysis, the degradation of new wedding dresses system BER caused by linear and parabolic group delay are obtained, and adaptive equalization to compensate group delay distortion is proposed.
