Mobile users on certain OFDM subchannels may experience deep frequency-selective fading in a multipath propagation environment.
The figure shows the performance of the MMSE-based algorithm to M-ary chirp-rate signal in deep frequency-selective fading environment.
Everything has emerged from the eternal pulse of the one Creation, from a deep frequency of quietude, which makes our heart beat, orders our thoughts and animates all life.
These songs are going to sound off to someone acclimated to the deep swing and bass frequencies of American music — it's not an instant sell.
The deep-frequency music grew louder by degrees, nearly past pleasure into discomfort, but not quite.
The result is deeper frequency excursions during system frequency disturbances [1].
Moreover, they located the foci of low-frequency earthquakes (deep low-frequency earthquakes, DLFEs) that cluster just below the sill-like deformation source; finally they inferred the existence of a second low-velocity zone extends in and around the caldera at a depth of 15 23 km.
Then tilt the phone forward/down to filter out the high end and just get the deep, low frequencies like you're dancing underwater.
For much of the hour, sheets of deep, complex frequencies so consumed the space that it became a kind of silence, a wash of low and midrange texture that roared through the room with a focused consistency.
Since waveforms of the earthquakes include high-frequency (> 10 Hz) energy, these earthquakes cannot be deep low-frequency earthquakes, which have a dominant frequency of 2 4 Hz and virtually no energy above 8 Hz (e.g., Hasegawa and Yamamoto 1994; Ukawa 2005).
