Abstract:
The ARTM Tier-2 waveform, called “ARTM CPM” in IRIG 106-04, has almost three times the spectral efficiency of PCM/FM and approximately the same detection efficiency. The improved spectral efficiency comes at the price of computational complexity in the receiver. The optimum receiver requires 128 real-valued matched filters and keeps track of the waveform state with a trellis of 512 states and 2048 branches. Various complexity reducing techniques are applied and the resulting loss in detection efficiency is quantified. It is shown that the full 512-state trellis is not required to achieve the desired detection efficiency: two different 32-state configurations were found to perform within one tenth of a dB of optimal. Noncoherent techniques are also evaluated. It is shown that the required complexity can be quite large to achieve a respectable detection efficiency. One noncoherent technique performed within 1.9 dB of the optimal with only 64 states, which is significant when considering the additional complexity savings of not having to track the carrier phase.
