Patent ID: 8619548

Claim:
A processing method in a joint transceiving mode determining whether a fault occurs on a direct channel by detecting a change of total energy of signals transmitted on the direct channel; after a fault is detected on the direct channel, stopping sending signals the direct channel with fault; detecting whether the direct channel with fault has been recovered based on a detection result of a detection signal that is sent on the direct channel after the fault is detected; and when recovery of the direct channel with fault is detected, resuming sending signals on the direct channel; wherein determining whether the fault occurs on the direct channel by detecting the change of the total energy of the signals transmitted on the direct channel comprises: getting squares of discrete values on a frequency domain, and adding the squared sampling values to obtain a detection value; comparing the detection value with a standard value; and if a ratio of the detection value to the standard value is smaller than a preset threshold value, determining that the fault occurs on the direct channel.
