AbstractSolving the two-antenna problem for the ARTM CPM waveform requires optimal estimation for a number of unknown signal parameters at the receiver to enable a space-time block-coded solution. To accomplish the required parameter estimation, known pilot bit sequences are added to the data structure of the transmitter. The degree to which optimal detection may occur for these unknown parameters is a function of the specific pilot sequences chosen. This paper outlines the principles for designing the pilot sequences, lists the chosen sequences explicitly, and shows that the pilots achieve the lowest Cram´er-Rao lower bounds in the estimators for several of the key parameters. These pilot sequences are to be used in implementations of space-time coded ARTM CPM aeronautical telemetry systems.
