Abstract

The invention relates to a sending terminal for implementing DS-UWB. The invention comprises: an encoder for decoding data frames to send, a spread spectrum modulator capable of performing PN sequence spectrum spreading and BPSK modulating to the data outputted by the decoder, a waveshaper capable of performing wave shaping to the data outputted by the spread spectrum modulator to get digital baseband waveshape, a digital-to-analog converter capable of performing digital-to-analog conversion to the digital baseband waveshape outputted by the waveshaper to get simulative baseband waveshape, a low pass filter capable of performing low pass filtering to the simulative baseband waveshape outputted by the digital-to-analog converter; an up-converter capable of performing up conversion to the simulative baseband waveshape outputted by the low pass filter, and an RF signal emission processor capable of performing emission processing to the signal outputted by the up-converter. The sending terminal for implementing DS-UWB also comprises a corresponding transmitting method, a receiving terminal and receiving method of the receiving terminal, which can overcome the difficulties in chipping DS-UWB technology in the prior art.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a transmitting end, a receiving end and a method thereof for realizing low-complexity DS-UWB (Direct Spread Ultra Wideband) based on a single carrier. Background technique [0002] With the increasing development of wireless communication technology, WPAN (Wireless Personal Access Network, wireless personal area network) technology is also more and more widely used due to its maturity. As part of the PHY (Physical Layer, physical layer) standard of high-speed WPAN, the realization scheme of UWB (Ultra Wideband, ultra-wideband) is generally considered to include two types: one is the DS-UWB scheme advocated by companies such as Motorola; the other is The OFDM-UWB (Orthogonal Frequency Division Multiplexing UWB, Orthogonal Frequency Division Multiplexing UWB) scheme advocated by Intel and other companies has not yet released a unified UWB standard due to fier...
