Abstract
A first communication device can dynamically select a mode of communication (such as a MIMO mode or a SISO mode) to improve throughput. In selecting the communication mode, the first communication device may determine whether a powerline medium effectively supports multi-channel communication. Even when the first communication device and a second communication device both are capable of using a MIMO mode, the first communication device may select a SISO mode if it determines that one of the channels is ill-conditioned for communication. For example, the powerline medium may be affected by a missing conductor, protective circuit, or other attenuation that impairs the second channel differently than the first channel. If the disparity between the first channel and the second channel is greater than a threshold, the first communication device may switch to a SISO mode to improve performance.
