This paper shows how the potential performance of ARTM signal [1] demodulator is related to its aperture and digital quantization noise. The first parameter (aperture) is a function of the architecture, while the second (quantization noise), depends on the digital implementation [2] of demodulator. Unified representation of the demodulator architecture as a matrix to vector product with the subsequent choice of maximum energy term was used in this paper to model performance of the demodulator for constant-envelope signals such as Tier-0 (PCM/FM), Tier-I (BPSK, QPSK, OQPSK, SOQPSK), and Tier-II (multi-h CPM). We will demonstrate how, when given a level of quantization noise and aperture width defined by the demodulator implementation, we can predict demodulator performance. Matlab/Simulink models demonstrating the performance of some demodulators will be presented and discussed.Sponsors
