In this paper a measure of performance of time delay estimators arising from a frequency model of the received signal is presented. The aim is to derive theoretical analysis of the Cramer-Rao bound (CRB) for time delay estimation under realistic wireless channel propagation conditions. The derivati...
Data can be in the frequency domain or the time domain. You can convert objects from one domain to the other. In the time domain, the data can be uniformly or nonuniformly sampled. To use the iddata object for estimation, however, the data must be uniformly sampled, and the input and ...
Making the time domain measurements utilizing a Time Domain Reflectometer (TDR) to apply a synthesized step waveform to a DUT and observing the response. Then the measured time domain information is converted to the frequency domain using the Fast Fourier Transform (FFT). In a linear network, th...
The default maximum plot time in the TDR Options dialog is related to the delta frequency df in the frequency sweep: it is 1/2df, since that is the extent of time for which the IFFT gives information. This is often very long relative to the time delay that corresponds to the length of...

Similar to the discussion on SSB transmissions, for 5G advanced, we propose that the frequency of PRACH occasions be changed dynamically rather than only semi-statically, as specified today. With the introduction of dynamic adaptation of PRACH occasions in the time domain, we can save energy...

delay in a system it must be done under a range of true operation conditions, not just the perfect golden laboratory conditions which give very favorable results. The ONT’s wide range of built- in stressor features including dynamic skew, frequency variation and error injection can be used to...
Huawei collaborated with operators to create the innovative Super Uplink solution. This innovation enables high-low band coordination, TDD-FDD complementation, time-frequency domain aggregation, and full-slot scheduling. As such, data rate is greatly increased while delay is significantly reduced in the...
