Patent ID: 8665935

Claim:
A method for calibrating a transmitting system for transmitting data from a medium access control device via a digital interface to a physical layer and an antenna to a transmission line, wherein the physical layer comprises a base band controller and a data processing pipeline comprising a plurality of functional blocks, comprising the following steps: setting a calibration control register, thereupon, setting the transmitting system to a calibration mode based on the setting of the calibration control register, wherein the transmitting system generates a predetermined number of single test tones and transmits the test tones sequentially via the antenna, and after transmission of the test tones via the antenna, detecting signals that are returned in response to the transmitted test tones and measuring their power levels and the spectrum behaviour of the transmission line, wherein the method comprises initializing a zero frame transmission or a transmission of a frame, whose length is correlated with a tone measurement time length of the single test tone, using the medium access control device.
