The effect of the frequency offset on the probability of miss in a packet modem using CFAR detection method (satellite communication)

The effect of frequency offset on the probability of miss for a packet radio modem, using the constant false alarm rate (CFAR) preamble detection scheme, is analyzed. The expression for the probability of miss for the general case, i.e., where there is a frequency offset, is derived. This general expression is then used to derive the expressions for the false alarm rate and the probability of miss for the special case where the frequency offset is negligible. Several graphs depicting the probability of miss for different values of signal-to-noise ratio and frequency offset are also included.<
