Description

(1) Technical field [0001] The invention relates to an FPGA (Field Programmable Gate Array, Field Programming Gates Array)-based ultra-wideband radio frequency digital receiver device and a realization method thereof. belongs to the field of communication. (2) Background technology [0002] The concept of UWB (UWB: Ultra Wide Band) was first proposed by the U.S. military in 1989. In April 2002, the U.S. Federal Communications Commission gave two definitions of UWB signals, one is the -10dB absolute bandwidth of the signal Not less than 500MHz, the other is that the -10dB relative bandwidth of the signal is not less than 20%. Systems whose signal bandwidth satisfies the definition of UWB signals are collectively referred to as UWB systems. [0003] The main advantage of ultra-wideband communication is that it can obtain extremely low power spectral density similar to Gaussian white noise, which basically does not affect the existing wireless communication system, so that it...
