A combination scheme made from different delay reduction schemes has been introduced, the first delay reduction scheme was shown in reference[47], and argues about performing fine sensing for non-real time traffic, while real time traffic continues transmission on the channel. The second scheme shown in reference[46], performs multiple alarms detection on the channel for a precise detection of the original signal return to the channel. Our scheme combination shows an improved reduction in the signal Delay and is shown by simulation results and graphs.
