Embodiment Construction

[0026] Specific embodiments of the present invention are described with reference to the above drawings.

[0027] Such as figure 1 As shown, this two-step acquisition method of ultra-wideband pulse signals based on energy detection includes the following steps:

[0028] A. First search the energy window where the signal component is located, calculate the detection probability of the energy window where the direct path signal is located, and determine the energy window where the direct path signal is located;

[0029] B. Determine its precise position within the energy window where the direct path signal is located.

[0030] The invention firstly searches the signal components, determines the energy window where the DP is located, and then determines its precise position within the energy window where the DP is located. The accuracy of capturing signals is improved, a large amount of calculation work is reduced, and the detection efficiency is improved.

[0031] In the step...

Abstract

A ultra-wideband pulse signal two-step acquisition method based on the energy detection is divided into two main steps: first searching the energy window of the signal component, through the Neyman-Pearson rule, computing the detection probability of the DP energy window through the energy statistic characteristics of the UWB channel under the condition with certain false alarm probability; determining the precise position inside the energy window of DP. The invention overcomes the defect of low signal detection precision and larger operand of DP signal in the prior art, which not only advances the precision to acquire the signal but also reduces the cost of the hardware, increases the detecting efficiency.

Description

technical field [0001] The invention relates to communication technology, in particular to the detection of ultra-wideband pulse signals. Background technique [0002] UWB (UltraWideband) is a carrier-free communication technology that uses nanosecond to picosecond non-sinusoidal narrow pulses to transmit data. By transmitting extremely low-power signals over a wide frequency spectrum, UWB can achieve data transmission rates from hundreds of Mbit / s to several Gbit / s within a range of about 10 meters. UWB has many advantages such as strong anti-interference performance, high transmission rate, extremely wide bandwidth, low power consumption, and low transmission power. It is mainly used in indoor communication, high-speed wireless LAN, home network, cordless phone, security detection, position determination, radar, etc. field. At present, it is formulated as the preferred physical layer technology of WPAN (Wireless Personal Area Network) by IEEE802.15.4a working group. [...
