Abstract:
1. A method for equalizing a transmission spectrum of a wireless communication transmitter, comprising: providing a plurality of single-frequency signals; respectively inputting the plurality of single-frequency signals into the transmitter, wherein each single-frequency signal has a predetermined frequency and all the predetermined frequencies are different from each other; loopbacking the plurality of single-frequency signals to an analog to digital converter so as to generate a plurality of digital loopback signals; calculating a frequency response of the transmitter at a base band circuit according to the plurality of digital loopback signals; and equalizing the transmission spectrum of the transmitter according to the frequency response of the transmitter; wherein the method is for the Wi-Fi wireless local area network; wherein each of the single-frequency signals has a frequency selected from the group consisting of 5MHz, 40MHz, 80MHz, -5MHz, -40MHz and -80MHz.
