Abstract
The systems and methods disclosed herein are generally directed to the real-time symbol rate of modulation modification based on noise and interference detection on a received signal during data transmission across a network. In one embodiment, a receiving device can measure the power of affected carriers, subcarriers, and/or tones. In one embodiment, adaptive bit loading can be used such that a lower order modulation scheme can be used to overcome through the noise and increase the Signal-to-noise ratio (SNR) of the transmitted signal. In one embodiment, more throughput (for example, more bps/Hz) can be achieved in the network by using subcarriers that have a higher SNR. Further, the bit-loading can serve to maximize the data rate subject to power and bit-error ratio (BER) constraints of the network.
