Abstract

In free space optical homodyne receiver that analyze Residual carrier COSTAS loop, in the pointing and communication phase with laser terminal analyze free space link optical power penalty and pointing power penalty. In the conforming bit error rate with BPSK homodyne receiver dues to the minimum receiver optical power, in the same way the relation between receiver optical power and homodyne locked phase error variance, and the relation between receiver optical power and homodyne optimum equivalent noise loop bandwidth, all the more loop filter design parameter is variable with receiver optical power. In simulation COSTAS loop homodyne locked phase error deviation and loop bandwidth, when the receiver power is more -50dBm and less -40dBm in the signal trace, COSTAS loop parameter is not appreciable on the whole. Locked phase loop is integrated in the relation between baseband phase error deviation and carrier frequency shift, when baseband phase error is 10 degree, carrier frequency shift about above 100MHz.
