Description: 分析了在超宽带通信系统中的扩频干扰，并用两种通用的调制技术实现了对提出的抗干扰方法的仿真-he ultra wideband (UWB) interference to direct
sequence spread spectrum (DSSS) receiver is analyzed. Two
popular UWB modulation schemes, the time hopping pulse
position modulation (TH-PPM) and time hopping pulse
amplitude modulation (TH-PAM), are considered. The pulse
repetition rate (T’RR) of UWB signal and the freqnency hand of
the DSSS play the primary roles in the BER performance of the
DSSS receiver in the presence of UWB interference. The UWB
signal parameters raising the interference to DSSS receiver are
discussed. The characteristics of an aggregation of multiple
UWB signals are somehow different from that of a single UWB
device, especially for the TB-PPM scheme, where discrete
spectral lines maybe exist in the band of DSSS receiver. The
system parameters of TH-PPM such as the modulaiion index
and maximum shift incurred hy the time hopping code
determine the amplitude of the discret Platform: |
