The present invention provides a unique feedback system in a wireless communication
system wherein the transmission channel is always overloaded with data, which is
configured and modulated at a select order of modulation. Based on the channel
conditions, only a portion of the data can be successfully received. As such, the
receiver will attempt to receive the data using demodulation techniques corresponding
to the different levels of modulation used to encode the data transmitted. The
receiver will determine the data that is recovered, or the highest order of modulation
at which the data is recovered, and provide feedback to the transmitter. The transmitter
will then retransmit the data that was not properly received. By overloading the
channel at all times, the maximum amount of data capable of being transmitted over
the channel is optimized without requiring or heavily relying on the receiver feeding
back channel condition information to the transmitter.
