| Abstract: | In nonsinusoidal digital communication system of PSWF, It can＇ t be ignored for system that the influence of truncation error and round-off error of the binary fixed point data. Firstly, this paper ana- lyses the reasons of the finite word length effect existence for the binary fixed point data. Then, the theory of truncation error and round-off error are analysed. In addition, the errors for the specific parameter in the communication system of PSWF are simulated using MATLAB. Induction and summary are made a- bout the results of simulation and it can offer the reference for engineering application. |
