Abstract:
1. A method for determining a common bit-loading modulation scheme for communicating between a plurality of nodes in a broadband cable network (“BCN”), the method comprising: transmitting a probe signal from a transmitting node within the plurality of nodes to a sub-plurality of receiving nodes within the plurality of nodes; receiving a plurality of response signals from the sub-plurality of receiving nodes wherein each response signal includes a bit-loading modulation scheme determined by a corresponding receiving node; comparing the plurality of bit-loading modulation schemes from the corresponding received plurality of response signals; determining the common bit-loading modulation scheme based on comparing the plurality of bit-loaded modulation schemes from the corresponding received plurality of response signals; and transmitting a broadcast signal from the transmitting node to the plurality of receiving nodes, wherein the broadcast signal utilizes the common bit-loaded modulation scheme.
