Abstract
A processing method and a transceiver for channel changing in a joint transceiving mode are provided. The method includes: performing fault detection for one or more direct channels; after a fault is detected on a direct channel, stopping sending signals on the direct channel; detecting whether the direct channel with fault has been recovered; and when recovery of the direct channel with fault is detected, resuming sending signals on the direct channel.
Claims10
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.
A transceiver system, comprising a transceiver, wherein the transceiver comprises:
- a fault detection unit, configured to perform fault detection for one or more direct channels implementing joint transceiving processing;
- a sending stopping unit, configured to stop sending signals on the direct channel with fault when detecting a fault on a direct channel;
- and
- a fault recovery detection unit, configured to detect whether the direct channel with fault has been recovered;
- wherein the fault detection unit comprises:
- a detection value determining module, configured to get squares of discrete values on a frequency domain, and adding the squared sampling values to obtain a detection value;
- and
- a comparison and fault determining module, configured to compare 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, determine the direct channel with fault.
A data transmission system comprising:
- at least two transceivers and at least two direct channels connected to the at least two transceivers, wherein each transceiver comprises:
- a fault detection unit, configured to perform fault detection for one or more direct channels implementing joint transceiving processing;
- a sending stopping unit, configured to stop sending signals on the direct channel with fault when detecting a fault on a direct channel;
- and
- a fault recovery detection unit, configured to detect whether the direct channel with fault has been recovered;
- wherein the fault detection unit comprises:
- a detection value determining module, configured to get squares of discrete values on a frequency domain, and add the squares to obtain a detection value;
- and a comparison and fault determining module, configured to compare 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, determine the direct channel with fault.
