摘要 通过分析了超宽带(ultra wideband)通信系统在多用户干扰和加性白噪声条件下的相干解调软判决的性能,给出了THMA-UWB在准高斯近似假设下的误码率求解公式,从而在系统设计时能更加容易地估计系统的性能。使用MATLAB软件在不同用户数下进行计算和仿真,得到性能曲线。得出在较多用户数时,理论计算和仿真基本一致的结论。 The ultra wideband time-hopping multiple access system＂ s performance of coherent demodulation and soft decision is analyzed under multi-user interference and added white noise condition. A solution equation of error rate is presented, while the MUI is assumed as a mean Gaussian process. Consequently the system＂ s performance is easy to be estimated at the beginning of system design. Performance chart is got by using MATLAB software, which calculates and simulates on different users number. A conclusion that theoretical calculation and simulation result is uniform approximation is got.
