摘要 在多用户和高斯信道的情况下,对采用多进制PPM调制的TH-UWB系统信道容量进行了分析和研究,并在满足FCC频率掩膜要求的基础上,计算了使用PSWF脉冲时的UWB信道容量,并与五阶和七阶高斯脉冲进行了比较。仿真结果表明,相同条件下采用PSWF脉冲的UWB系统具有更高的信道容量。该结论给出了一种从信道容量的角度选择脉冲的新方法,对于提高UWB系统的有效性具有一定的指导意义。 The channel capacity of M-ary PPM TH-UWB communication systems in the multiple-access and additive white Gaussian noise（AWGN） channel is investigated.The channel capacity of UWB system with PSWF pulses subject to FCC spectral masks is computed,and the results are compared with that of 5th and 7th order Gauss pulse.The simulation results demonstrate that the UWB system with the PSWF Pulse has more channel capacity than the system with Gauss Pulse.Based on this conclusion,a new method to select the pulse according to the channel capacity is obtained,and it is helpful and instructional to improve the efficiency of the UWB system.
