Propose an efficient and reliable transmission scheme for broadcasting and television satellite communication systems. By constructing a simulation experiment platform,comprehensive testing and evaluation of the key technical indicators of the system were conducted. The experimental results show that the designed system has excellent transmission performance and spectral efficiency in complex satellite communication environments,with carrier to noise ratio thresholds of 12 dB (uplink) and 16 dB (downlink),respectively. It can effectively resist channel fading and interference,ensure transmission quality,and provide important references for the design and optimization of broadcasting and television satellite communication systems.
