| 发明名称 | Method of measuring error vector magnitude | ||
| 摘要 | A method of checking an error vector magnitude of transmitter in accordance with some embodiments of the inventive concept may include dividing a transmission baseband signal which the transmitter transmits into a plurality of processing units; performing a transmitter function and an ideal receiver function with respect to each of the plurality of processing units; generating a reception baseband signal by recombining a processing result of each of the plurality of processing units; and calculating an error vector magnitude (EVM) by comparing the transmission baseband signal with the reception baseband signal. A simplified method of checking an error vector magnitude of transmitter in accordance with some embodiments of the inventive concept may include generating symbols composed of only pilots; generating symbol composed of only data; and checking an error vector magnitude (EVM) using the all the symbols. | ||

| 主权项 | 1. A method for calculating an error vector magnitude (EVM) of a transmitter comprising: dividing a transmission baseband signal which the transmitter transmits into a plurality of processing units; performing a transmitter function and an ideal receiver function on each of the plurality of processing units; generating a reception baseband signal by recombining a processing result of each of the plurality of processing units performed in the performing step; and calculating the error vector magnitude (EVM) by comparing the transmission baseband signal with the reception baseband signal. | ||
