摘要： A method for converging on a route through a radio frequency (RF) communications network, that includes multiple nodes, includes (a) identifying all RF links between each node in the RF communications network; (b) determining a connectivity confidence interval for each RF link by: (aa) developing a calculated signal to noise ratio using a radio frequency communication link propagation loss model; (bb) determining a threshold signal to noise ratio based on a predetermined RF packet completion rate; (cc) determining a standard deviation value based on a signal strength and a noise level at a signal receiving node; (dd) calculating a Z number, associated with a normal distribution table which is based on the threshold signal to noise ratio minus the calculated signal to noise ratio with that result being divided by the standard deviation value; and (ee) assigning a CCI probability value based on said Z number. The method further comprises (c) setting a predetermined connectivity confidence interval minimum; (d) comparing each connectivity confidence interval for each RF link to the predetermined connectivity confidence interval minimum to determine which are greater than or equal to the predetermined connectivity confidence interval; (e) assembling each RF link corresponding to each connectivity confidence interval that is greater than or equal to the predetermined connectivity confidence interval together to identify various routes through the RF network; (f) calculating a resultant connectivity confidence interval for each route by multiplying together each connectivity confidence interval for each RF link of each particular route; and (g) comparing each resultant connectivity confidence interval to identify the route with the greatest resultant connectivity confidence interval. An apparatus for carrying out such a method is also presented.

摘要： A system and method for optimizing transmission of radio frequency communication link signals in a radio frequency communications network comprises determining a statistical difference between a mean radio frequency communication link propagation loss value based on a set of measured radio frequency communication link propagation loss values, and a radio frequency communication link propagation loss model value; calculating a signal to noise ratio of a radio frequency communication link signal; computing a confidence interval based on a measured signal to noise threshold ratio of a measured radio frequency communication link signal, and a standard deviation associated with the calculated signal to noise ratio; assigning a probability value based on the confidence interval; and generating a radio frequency communication link packet completion rate performance level based on the probability value. The transmission of radio frequency communication link signals occurs in either jamming or no jamming situations.

摘要： This invention identifies a process for determining the performance of radio frequency (RF) links in the Army's Enhanced Position Reporting System (EPLRS) with a high level of statistical confidence. The method includes determining a statistical difference between a mean propagation loss for an EPLRS RF link based on measured RF propagation loss and TIREM calculated RF propagation loss, establishing a margin of error based on said statistical difference to arrive at a confidence level of the RF propagation loss, determining a computed S/N based on the confidence level, for the benign and jamming case, and determining a PCOM value based on the computed S/N value.
