narrowband interference การใช้

• Bluetooth Smart uses frequency hopping to counteract narrowband interference problems.
• This results in less ICI, as well as greater robustness to narrowband interference.
• In multi-diversity, e . g ., to mitigate frequency-selective fading or narrowband interference.
• Unlike a conventional communication system, however, a DSSS system does have a certain resistance against narrowband interference, as the interference is not subject to the process gain of the DSSS signal and hence the signal-to-interference ratio is improved.
