the transmission rate

As the UWB technology is a kind of radio technology sharing frequency band with other kinds of radio technologies, it is crucial to deal with the interference problem between the UWB communication systems and narrow band communication systems for the further development of UWB systems.In this thesis, I studied the modulation of UWB communication system. I analyzed discount wedding dresses and compared some of the advantages of BPSK modulation, which apply for the theory in the follow-up study.I research the interference between UWB communication systems and NB communication system. I derived the espression of the signal-to-noise (SNR) of the NB system and the SNR of the UWB system respectively. And discussed the influence of the NB signal and the UWB signal parameters which to cheap wedding gown dresses noise ratio. Then we use the computer simulation to verify the correctness of the theory analysis. The study shows that enhancing the transmission rate of the NB system will result in the higher BER of the NB system and enhancing the transmission rate of the UWB system the flat iron shop for us will result in the higher BER of the UWB system.Finally, I research the interference sell discount wedding dresses between UWB and Bluetooth audio systems. Through set up the system model, blog new shirts 2010 analyse the Bluetooth voice system and bit-error rate parameters, discussing the interference between UWB system for Bluetooth voice systems. Computer simulation results show that: a UWB system can coexist with Bluetooth voice system without causing any serious interference.
