| Abstract: | The paper study the channel detection protocol of the third generation automatic link establishment（3G-ALE）,to improve the deficiency of fallible detection,a new protocol of channel detection was proposed.At the synchronous model,the 8psk method have been popular used to find if the channel is idle in 3G-ALE.With low SNRs （signal-to-noise-ratio）,the outcome of this 8psk method is unbelievable, and it will result in the collision in trafficchannel after the automatic liink establishment.To solve the above problem,we propose an algorithm of channel detection based on the special data frame,Simulation results show it has a more better outcome of channel detection to the 8psk method even with low SNRs. |
