In more detail, radio element 112 can be configured to emit microwave radiation in a 1 GHz to 300 GHz range, a 3 GHz to 100 GHz range, and narrower bands, such as 57 GHz to 63 GHz. This frequency range affects radar antenna 114's ability to receive interactions, such as to track locations of two or more targets to a resolution of about two to about 25 millimeters. Radio element 112 can be configured, along with other entities of radar system 104, to have a relatively fast update rate, which can aid in resolution of the interactions.

Teachings discussed herein are directed to a cost-effective method and system for artificial bandwidth extension. According to such teachings, a narrow-band digital audio signal is received. The narrow-band digital audio signal may be a signal received via a mobile station in a cellular network, for example, and the narrow-band digital audio signal may include speech in the frequency range of 300-3400 Hz. Artificial bandwidth extension techniques are implemented to spread out the spectrum of the digital audio signal to include low-band frequencies such as 100-300 Hz and high-band frequencies such as 3400-8000 Hz. By utilizing artificial bandwidth extension to spread the spectrum to include low-band and high-band frequencies, a more natural-sounding digital audio signal is created that is more pleasing to a user of a mobile station implementing the technique.

A straight-forward approach to restore the low-band signal is then to counteract the effect of this channel transfer function within the range from 0 to 300 Hz. A simple way to do this is to use a low-band spectrum estimator 511 to estimate the channel transfer function in the frequency range from 0 to 300 Hz from available data, obtain its inverse, and use the inverse to boost the spectral envelope of the up-sampled narrow-band speech.

The test results displayed in FIGS. 11 and 12 indicate that the use of the dampening foam 68 (FIG. 6) provides effective vibration damping represented by good transmission loss performance, particularly in the frequency range between 600 to 2,000 Hz where shear deformation was the dominant wave propagation mechanism. The use of dampening particles 66 also provided good vibration damping illustrated by improved transmission loss performance compared to the baseline panel 4. It was also found that increasing the depth of the core 26 a had a somewhat adverse impact on transmission loss performance. Increasing facesheet thickness was found to improve transmission loss performance but moved the coincidence plateau of the panel lower, centered at 1600 Hz, resulting in a reduction of the transmission loss. The use of damping particles was found to provide significantly higher damping loss factor compared to the baseline panel 4, in the frequency range between 500 and 1,600 Hz.

FIG. 1 illustrates one embodiment of an acoustic panel 10 for effectively attenuating sound over a relatively wide range of frequencies and sound pressure levels. One side of the panel 10 is exposed to the sound, hereinafter sometimes referred to as acoustic waves 44. The acoustic panel 10 includes a single layer of cellular hexagonal core 12 (or other type of core to provide a local air column) having a first side 14, a second opposite side 16, and a plurality of individual cells 18 extending therebetween. The sizes of cells 18 can be selected to tune core 12 to acoustic waves having a particular frequency or range of frequencies. For example, and without limitation, the core 12 may be tuned to a frequency range of between approximately 800 Hz and 4,000 Hz.
