In terms of communication, DS UWB far exceeds traditional wireless communication technologies in terms of channel utilization, channel protection ability, and transmission rate. At the same time, due to its ultra-wideband characteristics, DS UWB can achieve high-precision positioning within a short distance and is suitable for multiple application fields such as indoor positioning, personnel tracking, and vehicle safety. Compared with traditional UWB technology, DS UWB emphasizes double-sideband modulation technology, which can reduce signal power, improve spectral efficiency, and has better multipath characteristics, enabling it to better adapt to signal transmission in various environments. In short, DS UWB is widely used in fields such as automotive, smart home, smart healthcare, and indoor positioning due to its advanced technical characteristics, bringing more convenience to people's lives.

[0030] 2. Pulse Modulation Method

[0031] The pulse modulation method is a commonly used digital communication method that can represent an analog signal as a digital signal composed of discrete pulses. The pulse modulation method usually includes the following types:

[0032] Pulse Amplitude Modulation: Quantizes the amplitude of an analog signal into the size of the pulse amplitude and is usually used for digital audio and video transmission.

[0033] Pulse Width Modulation: Converts the amplitude of an analog signal into the pulse width and is usually used in applications such as motor control and LED dimming.

[0034] Pulse Position Modulation: Converts the amplitude of an analog signal into the pulse position and is usually used for digital modulation and position measurement in communication systems.

[0035] In the pulse modulation method, the basic characteristics of the pulses are their width, amplitude, position, and density. These characteristics are represented as discrete values in the digital signal and can be conveniently processed digitally. The main advantage of the pulse modulation method is that they can effectively resist noise and attenuation and provide high-quality signal reconstruction, making it an important part of modern digital communication systems.

[0036] 3. Pulse Waveform

[0037] A pulse waveform is a waveform composed of a series of rapidly changing pulse signals. It is usually composed of pulses with very steep slopes and can be transmitted by means such as remote controls, radars, and radio communications. Common pulse waveforms include:

[0038] Rectangular pulse: The period of this pulse waveform is T, and it includes two states, high level and low level, and has the characteristics of a square wave.

[0039] Sine pulse: The period of this pulse waveform is T, and it includes two signals, sine wave and pulse, and its shape is similar to a sine curve.

[0040] Gaussian pulse: This pulse waveform is a bell-shaped curve and is commonly used in fields such as radars and radio communications and has ultra-wideband characteristics.

[0041] In communication and radar systems, the characteristics of pulse waveforms are crucial for transmitting and receiving signals. They can be used to identify information such as the distance, speed, and direction of a target, and at the same time can provide high-quality transmission and reception in environments with low signal noise and multipath propagation. Therefore, pulse waveforms are widely used in radar and radio communication systems.

[0127] Exemplarily, the above first configuration includes the frequency-domain allocation information based on a pulse waveform. For example, if the data transmission is a pulse waveform, the frequency-domain default allocation is the BWP bandwidth or carrier bandwidth. Another example is that the frequency-domain allocation information of the data transmission is related to the frequency domain of the control channel.
