Patent ID: 6909755

Claim:
A method for increasing data throughput in a communications channel comprising the steps of: selecting a first data packet from a queue of data packets to be transmitted over said communications channel; modulating said first data packet using a first modulation scheme; selecting a second data packet from a queue of data packets to be transmitted over said communications channel; modulating said second data packet using a second modulation scheme overlaying said first data packet; transmitting said first data packet overlaid with said second data packet over said communications channel; determining whether said first data packet was received by monitoring using said first modulation scheme for an acknowledgment for said first data packet before expiration of a timeout period; determining whether said second data packet was received by monitoring said first modulation scheme for an acknowledgment for said second data packet before expiration of said timeout period; and repeating all of the the steps outlined above, if acknowledgments were received for both said first and said second data packets.
