| 摘 要： | 将正交小波引入到UWB系统中,利用小波函数和尺度函数的正交性,来减小多址干扰对接收信号的影响。分析了高斯脉冲和3种小波函数在多进制情况下的系统误码率特性,并进行了误码率特性的比较。实验证明,在已知的传输速率的情况下,进制数越高误码率性能越好,但会受到用户数的制约。其中,dbN和coifN小波系的误码率性能优于高斯脉冲,meyer小波性能较差。

| Abstract: | In this paper the orthogonal wavelets are introduced in the UWB system,using the orthogonality of the wavelet function and the scaling function to reduce the multi-access interference (MAI).We analysis the BER performance of the Gaussian pulse and three kinds of orthogonal wavelets under the M-ary condition,and compare their different performance.According to the simulation,under the given transmitting rate we can find M is bigger,the BER performance is better,but it will be restricted by the number of users.And for the BER performance dbN and coifN are better and the Meyer is worse than the Gaussian pulse. |
