Abstract

The invention relates to an ultra-wideband receiving method based on the frequency division section parallel sampling and mainly comprises the following steps: converting multi-channel analog signals treated by each radio frequency module into multi-channel digital baseband signals; carrying out the pretreatment of synchronization and frequency-offset correction of the digital baseband signals; carrying out frequency diversity of pretreated data on different carrier frequencies; recovering and treating the data after the frequency diversity and obtaining the received data needed. The invention also relates to a receiving terminal which realizes an ultra-wideband system. A receiving method and the receiving terminal thereof which can realize the ultra-wideband system take full advantages of richer spectrum resources of the ultra-wideband system and adopt a baseband treatment scheme based on the frequency division section parallel sampling and the frequency diversity, which can effectively reduce the sampling rate of ADC and the operation bandwidth of radio frequency devices such as a low-noise amplifier, a frequency mixer, and the like, thus greatly reducing the difficulty and the complexity of designing ultra-wideband chips and realizing the system.

Description

technical field [0001] The present invention relates to the technical field of broadband wireless communication, in particular to a UWB (Ultra Wideband, ultra-wideband) receiving method and a receiving end thereof based on frequency-divided parallel sampling. Background technique [0002] With the rapid development of wireless communication technology, spectrum resources have gradually become the bottleneck restricting the development of the entire wireless communication. UWB has a series of advantages that can provide high-speed data transmission in short distances such as homes and offices without occupying additional spectrum resources. The strong demand for bandwidth provides an ideal path. [0003] At present, the development of UWB has entered the stage of chip realization and industrialization. Major companies mainly carry out UWB chip design based on the two technical solutions of DS-UWB and MB-OFDM. The main technical problems are as follows: [0004] 1. The UWB s...
