N2 - In order to obtain generalized simulation of Aerospace tracking, telemetry and control (Aerospace TT & C) channel, a simulation method based on equal interval sampling-unequal interval reconstruction is put forward in this paper. The method samples the input signal of the uplink and downlink at stated intervals, releases the sampled date by unequal interval clock which is based on the variation rule of the satellite-to-earth location, and then acquires the simulation signals by reconstruction filter. Comparing with existing methods, the method can be used in any working modes and systems. It can simulate the transmission effect of electromagnetic wave in the channel without knowing priori knowledge, such as the carrier frequency, code pattern, code rate, and so on. The theory and the arithmetic of the generalized simulation method and unequal interval clock generation will be analyzed in this paper.
