13 | | The experimental independent variable is gain of the variable gain amplifier in the MAX2829 transceiver at the transmit node. The Tx power controlled by a 6-bit digital value, which maps control values ![0,63] to Tx gains of approximately [-31, 0]dB. We sweep over control values of ![17,63] in our tests. The plot uses an x-axis of 'Channel Gain', which is the sum of the reduced Tx power and 80dB external attenuation. |
| 13 | The experimental independent variable is gain of the variable gain amplifier in the MAX2829 transceiver at the transmit node. The Tx gain is controlled by a 6-bit digital value, which maps control values ![0,63] to Tx gains of approximately [-31, 0]dB. A control value of 63 corresponds to maximum transmit power, which is the default for the OFDM Reference Design. We sweep over control values of ![15,63] in our tests. The plot uses an x-axis of 'Channel Gain', which is the sum of the Tx gain and the 80dB external attenuation. This axis is analogous to (and used as a proxy for) SNR. |
