Is it Ultra Wide Band (UWB)?
The relative energy bandwidth of the electromagnetic wavewaveform is greater than 0.2~0.25.
Understanding of waveform energy bandwidth?
Determined by the frequency FL and FH, if most of the energy of the waveform (greater than 90%, that is, -10dB radiation point, here -10DB means that the waveform energy 0DB drops to -10DB, and the energy drops from 1 to 0.1 energy. 0.9 energy, 0.1 energy left).
Definition: FH-FL
Upper and lower limit frequency FL and FH?
Definition: The latest UWB energy radiation standard released by the United States [FCC, 2002] defines the offline frequency FL and the upper limit frequency FH at the radiation point where the power spectral density is attenuated to -10DB.
What is an ultra-wideband signal (UWB signal)?
(1) The energy bandwidth of a signal is greater than one-fifth of the center frequency.
(2) Because the signal relative bandwidth = signal bandwidth/center frequency.
If the -10DB radiation point bandwidth in the signal energy (power) spectral density graph is greater than 500M, that is, 500M/center frequency=0,2, that is, the center frequency is 2.5GHz, and the signal can be roughly regarded as a UWB signal. (From the lower bandwidth of 500Mhz, a threshold of 2.5Ghz is obtained.)
Definition:
(1) The relative bandwidth of a signal is greater than 0.2~0.25.
(2) The bandwidth of the -10DB radiation point of a signal has exceeded 500MHz. Regardless of the relative bandwidth of the signal, it can be regarded as a UWB signal.
What is relative bandwidth?
The energy bandwidth of a signal is the percentage of the center frequency.
Definition: The ratio of the signal energy bandwidth to the center frequency.Signal energy (power) spectral density-frequency diagram?
Indicate the relationship between signal energy and frequency.
How to generate a UWB signal?
Since UWB signals are only defined from the frequency domain perspective (relative bandwidth/minimum bandwidth), there are many ways to generate UWB signals:
Impulse plan:
IR-UWB (Impulse Radio UWB)-Narrow Pulse
(1). Coding of data symbols (applying pseudo-random code or pseudo-random noise (PN) to encode information data symbols)
–The purpose is to form the required spectrum
A. TH-UWB (Time-Hopping UWB)
B. DS-UWB (direct sequence ultra-wideband Direct-Sequence UWB, in the case of non-IR, this modulation is called DS-SS direct sequence spread spectrum)
C. MB (multi-band)
D. Frequency-hopping spread spectrum
(2). Data modulation-pulse modulation (modulate the pulse with information data symbols)
A. PPM pulse position modulation
B. PAM pulse amplitude modulation
Non-impulse solution:
OFDM (Orthogonal Frequency Division Multiplexing)
MC-CDMA (Multi-Carrier Code Division Multiple Access)
Note: DS-SS OFDM MC-CDMA usually operates at radio frequency (baseband signal modulates carrier signal), but UWB is a typical baseband operation, so radio frequency modulation is rarely mentioned in UWB systems (RF modulation can also be used for UWB, the frequency change can be obtained through pulse formation).
