Come tradurreste "the nearest neighbour sampler"?

"The sample selector (63) selects, for each chip, the sample that most closely matches the desired ideal sample time. Where the latter is expressed in clock ticks, this is achieved by rounding each ideal sample time to the nearest integer. Since integer values of clock ticks correspond to input sample times, and therefore also to sample times of the CMF outputs, these rounded times (in ticks) correspond to actual samples out of the CMF, which are the samples selected."

"If the correlator is attempting to track, e.g. the "on-time" signal, then the ideal sampling point from the CMF will be at the end of each chip. Thus the nearest neighbour sampler (65) will choose the sample that is closest in time to the supposed edge of the chip, but, because of the rounding process the actual sample selected may occur either before the end or after the end of the supposed edge of the chip."

"Waveform (e) of Figure 6 is a simulated output of a matched filter, broadly similar to waveform (e) of Figure 4, but instead showing the sample times (i.e. the sample chosen to feed into the correlator for each chip) that are chosen by the SSU in embodiments of the present invention. Here, in this example, the "desired ideal" sampling time is at the end of each chip. The nearest neighbour sampler of Figure 6 is therefore programmed to select the nearest sample to that ideal point, and hence chooses the sampling points as indicated by circles on waveform (e)."
