Weibin Zhang · Journal of Huaqiao University · 2007
Under certain ratio of signal-to-noise(S/N) and through the computer simulations and calculations,the performances in Mbius digital base band communication system of five often used modem function set,those are the even and odd symmetrical triangle wave,even and odd symmetrical square wave and saw-tooth wave and their inverse transforms,are simulated 10 000 times,and the fluctuation ranges of the error rate(Pb) are observed.The simulation results show that the system is completely feasible.The error rates in different ratio of signal-to-noise are calculated and the figures of error rate to signal-to-noise are plotted out.The figures of error rate to signal-to-noise show that the new type system of Mbius digital base band communication system has much more excellent performance than the traditional system and it can decrease the initial investment and increase the cost performance.
