Abstract


Channel is the general term for the media between the transmitter and the receiver end , it is an important part of the communication system . Establish wireless channel model has important significance for the mobile communication system performance analysis and engineering applications . The subjects belonging to the telemetry radio channel simulation with a research institute of the cooperation project \In this paper, computational modeling and simulation of the launch site environment received signal loss . The content is divided into two parts , namely, the received signal loss calculation in the vehicle stationary state aircraft took off state analysis and simulation . For stationary model , respectively multipath model and the the Okumura model of two methods to calculate Points . The Okumura model by adding a different environment and terrain correction factor , which makes the calculation results the floor measured only theoretical analysis based on the more accurate. In the case of aircraft launch , consider launch the first 20 seconds of the time, the receiver receives a signal loss , the preliminary discussion . On this basis , also joined flame factors accordingly calculated . Finally, the performance simulation graphics to make a statistical analysis and simulation results .
