Sentence examples for spread and frequency from inspiring English sources

Histograms visualising the spread and frequency of contributions to the heterogeneity were also generated.

The worst possible scenario considered in terms of delay spread and frequency selectivity is B1 (urban microcell) with non-line-of-sight (NLOS) propagation; it has 20 channel taps and a delay spread of 485 ns.

We concluded that CoVs are widespread among wild birds in Beringia, and their geographic spread and frequency is higher than previously realised.

The spread and frequency of values is shown in Figure 1.

For practical purposes it is necessary that the statistics of the spread F occurrence distribution (from ionograms) be based, separately, on the range spreading and frequency spreading components of the spread F. The well known features of spread F include its day-to-day, seasonal and solar cycle variations.

While spread spectrum and frequency hopping techniques are important physical layer mechanisms for combating jamming, additional protection is required at the packet-level.

A related approach, called multicarrier block-spread (MCBS -CDMA, was introduced in [9] by capitalizing on redundant block spreading and frequency-doMCBS -CDMAr precoding to preserve orthogonal multiple-accessing and to enable full multipath diversity gains.

Syphilis' and chancroid's high per-contact infectiousness [45], [46], [49] promotes rapid spread and high frequency of genital ulcers in local sexually promiscuous settings (e.g., PSS may attain frequencies of 20 60% during initial invasion [45]).

The dramatic global spread and increased frequency and magnitude of epidemic DF/DHF in the past 40 years underscore the critical need for more effective surveillance, prevention, and control of this disease.

Broad use of antibiotics leads to rapid spread and high frequency of resistant strains, particularly in hospital and long-term care settings where rates of antibiotic use are the highest.

Parameter ϕ n (t) is the phase of the n th interfering signal uniformly distributed within the range [0, 2Π). The IEEE 802.15.4 uses spread spectrum techniques such as direct sequence spread spectrum (DSSS) and frequency hopping spread spectrum to reduce the effect of interference.
