What are the performance characteristics and limitations of UWB wireless communication?
1 The main advantages of UWB wireless communication
The main advantages of UWB wireless communication are as follows:
(1) From an engineering perspective, UWB is far simpler than other wireless technologies.
UWB can be integrated into a relatively inexpensive chip. Compared with the transmit power of cellular phones and civilian band devices, UWB only requires milliwatt-level transmit power. , Is 1/10 to 1/100 of the existing wireless system.
Therefore, the manufacturing cost and selling price of UWB products are much lower than the existing wireless systems.
(2) Generally speaking, multipath is not a major problem in UWB wireless systems.
Its GHz-level bandwidth corresponds to ns-level resolution so that multipath signals can be separated in time, plus the use of RAKE receivers combined with time Diversity can make full use of the energy of the transmitted signal.
Therefore, the limitation on the performance of the existing narrowband system by the multipath effect reduces UWB to some extent.
(3) It can have a very high data transmission rate.
UWB can provide a data rate of 100 Mbit/s in the range of 5 m to 10 m. Even the “802.11” wireless network technology (54 Mbit/s) and low energy Bluetooth technology (70 Mbit/s) are far from Compared to UWB. At the same time, the space capacity of UWB is much larger than that of traditional wireless technology.
(4) UWB is a safe communication method.
This is because the ideal impulse pulse can extend the signal energy from direct current (DC) to the frequency domain close to light waves in the frequency domain, but it cannot produce a width in practice.
For UWB, a very narrow pulse signal energy can span a considerable range in the frequency domain. The transmitted signal is evenly released in such a large frequency range and is submerged in environmental noise, which is difficult to detect.
(5) UWB has high penetrating power, and its ns-level high-speed pulse can penetrate walls and other objects and can play the same role as radar.
Therefore, in addition to being used in the communication field, UWB also has functions such as positioning, vehicle collision avoidance, ranging, and perspective, and these functions can all be integrated.
2 Limitations of UWB wireless communication
(1) A very practical problem that affects the use of UWB is the problem of interference.
There are two aspects here:
A. UWB interference to other wireless systems. Up to now, UWB has used a very wide bandwidth to send and receive radio signals, but in fact, there is no such wide free frequency band.
There must always be part of the frequency band with the existing wireless systems, such as aviation, military, security, astronomy, and other fields. The frequency bands used by the system overlap and even interfere with other narrow-band wireless communications such as GPS.
Therefore, UWB can only get limited applications at present. It can be said that UWB is a communication technology based on sharing other wireless communication frequency bands, and its potential or serious interference to narrowband systems is still under study.
B. UWB is interfered with by other wireless systems. If the UWB signal is lower than the threshold value of the traditional superheterodyne receiver, then the narrowband signal transmitted by the traditional transmitter will also be greater than the threshold value of the UWB receiver.
Therefore, it is very easy to be in the frequency band of the UWB receiver. The accuracy of the matched filter and the ultra-wideband antenna are not easily satisfied by the interference of the traditional narrowband communication machine.
(2) Other limitations.
A. Due to the short duration of the pulse, precise timing is required to receive the pulse as correlation detection. In addition, the noise generated by the onboard microcontroller is also a serious problem, because if it is a traditional transceiver, it is enough to suppress out-of-band noise, which is not feasible for UWB.
B. In essence, UWB can use a narrower pulse (to get a high signal/symbol rate) in exchange for the other two variable parameters, namely bandwidth (widening) and signal-to-noise ratio (S/N <reduction>).
However, to use a larger bandwidth, approval is required. At the same time, the signal at a high bandwidth will reduce the S/N on average, resulting in a decrease in signal/symbol rate and channel capacity (data rate).
If the goal of UWB is to obtain high channel capacity or high-speed data rate, it can be achieved by increasing the average pulse frequency above 2 GHz or increasing the power of the transmitted signal (if allowed and without causing interference).
It will be the same as a conventional wireless communication system, that is, the UWB system also needs to strike a balance between bandwidth efficiency, transmission peak power, complexity, flexible support for multiple rates, and performance expressed in BER.
