ABSTRACT:
A method of processing wireless signal of data pulses or packets in a communication system, in which a portion of the data pulses in an individual signal are utilized to determine a rate of time shift for eliminating or minimizing the effects of Doppler shift in the intra-data pulse processing. One embodiment of the invention provides a method of utilizing the time refinement section of a JTIDS waveform for the purpose of determining an intra-burst data correction factor based upon the average shift of the midpoint of the sampled time refinement section pulses.
