Abstract

A method and apparatus for pulse interference suppression, and a computer readable storage medium in a communication system are provided in the embodiments of the present invention. The method includes: judging a location where pulse interference occurs according to a power of a signal; and performing suppression processing on a data segment interfered by a pulse in the location. After judging that the pulse interference exists in the location, a receiver in the communication system discards the data segment interfered by the pulse in the location, and feeds back an indication that the data are not received.

First claim

What is claimed is:

1. A method for pulse interference suppression in a communication system, comprising:
determining, by a receiver in the communication system, a location where pulse interference occurs according to a power of a signal; and
performing, by the receiver, suppression processing on a data segment interfered by a pulse in the location;
wherein, said determining a location where pulse interference occurs according to a power of a signal comprises:
segmenting the signal according to a duration of the pulse interference, when the duration of the pulse interference is not fixed, segmenting the signal in units of a shortest duration of the pulse interference, and calculating a power of each segment of the signal; and
comparing the powers of every two adjacent segments of the signal in turn, and determining the location where the pulse interference occurs according to a ratio of the powers of every two adjacent segments of the signal, when the ratio of the powers of two adjacent segments of the signal is greater than a threshold value, determining that a pulse interference exists.

2. The method according to claim 1 , wherein, said performing suppression processing on a data segment interfered by a pulse in the location comprises:
after determining that the pulse interference exists in the location, discarding the data segment interfered by the pulse, and feeding back an indication that data are not received.

3. The method according to claim 1 , wherein, the threshold value is set according to amplitude ranges of the pulse interference and the signal in the communication system.

4. A non-transitory computer readable storage medium, comprising: a set of instructions, wherein the instructions are used for executing the method for pulse interference suppression in a communication system according to claim 1 .

5. A receiver for pulse interference suppression in a communication system, comprising hardware performing instructions stored in a non-transitory computer readable medium which executes following steps:
determining a location where pulse interference occurs according to a power of a signal; and
performing suppression processing on a data segment interfered by a pulse in the location;
wherein, said determining a location where pulse interference occurs according to a power of a signal comprises:
segmenting the signal according to a duration of the pulse interference, when the duration of the pulse interference is not fixed, segmenting the signal in units of a shortest duration of the pulse interference, and calculating a power of each segment of the signal; and
comparing the powers of every two adjacent segments of the signal in turn, and determining the location where the pulse interference occurs according to a ratio of the powers of every two adjacent segments of the signal, when the ratio of the powers of two adjacent segments of the signal is greater than a threshold value, determining that a pulse interference exists.

6. The apparatus receiver according to claim 5 , wherein, said performing suppression processing on the data segment interfered by the pulse in the location comprises:
after determining that the pulse interference exists in the location, discarding the data segment interfered by the pulse, and feeding back an indication that data are not received.

7. The apparatus receiver according to claim 5 , wherein:
the threshold value is set according to amplitude ranges of the pulse interference and the signal in the communication system.
