ZigBee
The designers of the radio portion of the standard looked for the most robust modulation method available, eventually choosing Quadrature PSK, the same technique that NASA has used for the past two decades to communicate with the deep-space crafts Voyager and Galileo, as well as the Mars rovers. The technique is based on the idea of phase-shift keying (PSK) modulation, in which the regularly oscillating peaks and troughs of a radio wave are suddenly jumped half a cycle, so that a peak comes when a trough is expected. The direction of the “discontinuous jump in phase” indicates the reception of either a 1 or a 0, a discontinuity so sharp that it can be detected even in inhospitable environments.

（被）向前调了半个周期
I agree with your argument. It seems to be an effect resulting from some step carried out by the scientists.
