BER Performance of Photon Counting PPM vs. DPSK for Satellite Communications
摘要：
本文用解析、统计的方法推导了M元PPM和双相DPSK调制在噪声存在下的误码率表达式。PPM表达式通过基于泊松统计的仿真进行验证。BER表达式，然后应用到一组代表性的接收望远镜和天空光谱辐射参数，以评估性能的PPM和DPSK相对于彼此。最后，讨论了效率和其他考虑因素。
英文摘要：
Expressions for the BER of M-ary PPM & biphase DPSK modulations in the presence of noise are derived using analytical, statistical methods. The PPM expression is verified via Poisson statistics based simulation. BER expressions are then applied to a representative set of receiving telescope & sky spectral radiance parameters in order to assess performance of PPM & DPSK relative to one another. Finally, efficiency & additional considerations are discussed.
