| Abstract(in English) | This paper evaluates the improvement in signal to noise power ratio (SNR) in the EPWM transmitter using power-amplifier-inserted transversal filter (TF) by employing window function in the TF by computer simulation with MATLAB/Simulink. In addition, the error vector magnitude (EVM) is calculated by demodulating the transmitter signal. As a result, the SNR was improved when the effective number of path is 256. In addition, the EVM is improved when the effective number of path is higher than 32. |
