Method and system for increasing data throughput in communications channels on an opportunistic basis

A method for 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 overliad 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 using said first modulation scheme for an acknowledgment for said second data packet before expiration of said timeout period;
• and
• using said second data packet as the selected first packet and repeating the steps outlined above commencing with said modulating step for said first data packet, if no acknowledgment was received for said second data packet prior to expiration of said timeout period.

A system for increasing data throughput in a communications channel comprising:

• means for selecting a first data packet from a queue of data packets to be transmitted over said communications channel;
• means for modulating said first data packet using a first modulation scheme;
• means for selecting a second data packet from a queue of data packets to be transmitted over said communications channel;
• means for modulating said second data packet using a second modulation scheme overlaying said first data packet;
• means for transmitting said first data packet overlaid with said second data packet over said communications channel;
• means for 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;
• means for determining whether said second data packet was received by monitoring using said first modulation scheme for an acknowledgment for said second data packet before expiration of said timeout period;
• and
• means for performing an iterative loop encompassing the system above, if acknowledgments were received for both said first and said second data packets.
