Problems solved by technology

[0007] In addition, the main information of the template signal comes from the strongest complete pulse signal, however, in the actual measurement environment, due to the interference of various scatterers, the multipath of the received signal is randomly distributed on the time delay
If the multipath signal is too close to the strongest main pulse signal in the time domain, mutual interference will occur, making it impossible to separate the complete strongest pulse from the received signal as a template signal
Especially in wideband channel measurement, due to the large time domain width of the pulse, the multipath overlap phenomenon is even more serious

Abstract

The invention provides a method for acquiring a template signal. The method comprises the following steps of: arranging a transmitting antenna and a receiving antenna; arranging metal plates in the directions of multi-path signals to block the multi-path signals, wherein the multi-paths are closest to a main path, and reach a receiving antenna after reflection; and separating a main path pulse signal serving as the template signal. The invention also provides a device for acquiring the template signal. By the method and the device for acquiring the template signal, measurement can be realized in an ordinary indoor environment, and is not required to be performed in a microwave anechoic chamber, so that measurement cost is lowered; and in addition, the interference of the multi-path signals can be blocked, so that a complete strongest pulse signal can be separated from a received signal, and is used as a wideband / ultra wideband template signal.

Description

technical field [0001] The invention relates to the field of time-domain measurement, in particular to a method and device for acquiring a broadband / ultra-wideband template signal. Background technique [0002] Statistical channel modeling through channel measurement requires relevant data processing of the received signal to extract the channel impulse response, so as to obtain an impulse response formula including multipath gain, delay, and phase of each channel: [0003] h = Σ k = 1 n a k e j θ k δ ( ζ - ζ k ) [0004] In the above formula, a k is the gain of the kth path; θ k is the phase of the kth diameter; ζ...
