| The signal detection performance is studied for an on-board switching broadband satellite IP network. The probability of false alarm, miss and false detection is analyzed and simulated.
Three cases have been considered: (A) The desired signal with AWGN; (B) The desired signal with AWGN and the presence of all interferers; (C) The desired signal with AWGN, all interferers and symbol timing error. It is shown that in the worst case, i.e., the desired sinal has the maximum symbol timing error and all of the interferers are present, the point-to-point can reach $10^{-19}$ as the total probability of packet loss in the packet detection stage using CFAR. In the worst case, the probability of packet loss is $10^{-21}$ in the Continental US in the packet detection stage. The threshold setting is discussed. Simulation results match theoretical results. |
