Description

Method and system for eliminating impulse noise of power line carrier receiver
Technical Field
The invention relates to the field of communication, in particular to a processing algorithm of a receiver aiming at special type noise in the field of power line carrier communication, and specifically relates to a method and a system for eliminating impulse noise of a power line carrier receiver.
Background
In the conventional power line carrier communication, two algorithms, namely, a zeroing algorithm (Blanking) algorithm and a clipping algorithm (clipping) algorithm, are mainly used for an impulse noise cancellation algorithm. For the performance of the receiver, the zero setting method is superior to the amplitude limiting method when the pulse strength is strong, and the amplitude limiting method is superior to the zero setting method when the pulse is weak.
In strong pulses, a nulling method that is only thresholded by the absolute amplitude of the signal may result in the presence of residual non-nulled points in the nulling interval, such as the sequence obtained by the classical algorithm in fig. 1, which points themselves may be too few consecutive points for the receiver to contain almost no information, and if not nulled, may result in poor receiver performance.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
A first aspect of the present invention provides a method for eliminating impulse noise of a power line carrier receiver, as shown in fig. 2, including the following steps:
step S100, for the actual sampling sequence of the receiver
Figure 776101DEST_PATH_IMAGE045
Generating a companion sequence
Figure 178132DEST_PATH_IMAGE046
As shown in fig. 3, in parallel with the actual sampling sequence; where n is the sample point. The low-pass processing of the present invention employs an FIR low-pass scheme. For actual sample sequence received by receiver
Figure 204994DEST_PATH_IMAGE047
Generating a companion sequence
Figure 858829DEST_PATH_IMAGE048
In parallel with the original sequence, if the signal sequence point exceeds the pulse threshold (assuming the pulse threshold is
Figure 287537DEST_PATH_IMAGE049
) It is marked as 1, otherwise it is marked as 0. The accompanying sequence
Figure 611202DEST_PATH_IMAGE050
The following formula is expressed as:
Figure 187677DEST_PATH_IMAGE051
（1）
wherein the content of the first and second substances,
Figure 317307DEST_PATH_IMAGE052
the recommended interval is [0.2,0.5 ] for pulse threshold]The value is selected in relation to the success rate of discrimination of pulses and the false discrimination of non-pulses as pulses. The smaller the value, the higher the success rate of discrimination but the higher the probability that a non-pulse point is discriminated as a pulse point, and the larger the value, the lower the recognition rate of a pulse but the lower the false discrimination rate that a non-pulse point is discriminated as a pulse point.
Step S200, the adjoint is passed through a low-pass filter having an impulse response of
Figure 787471DEST_PATH_IMAGE053
The adjoint sequence passes through the output signal of the low-pass filter
Figure 875513DEST_PATH_IMAGE054
As its convolution with the impulse response:
Figure 876967DEST_PATH_IMAGE005
（2）
in the formula，
Figure 607026DEST_PATH_IMAGE055
The value of (c) is related to the period of a typical pulse.
Since the adjoint sequence has information about whether the signal is a pulse signal, for a strong pulse signal, since the short-time energy is strong and the energy of other segments is weak, the adjoint sequence corresponding to the pulse signal segment has a continuous constant value 1, but due to the randomness of the pulse, in the adjoint sequence corresponding to the pulse signal segment of the receiving sequence, a sparse 0 signal exists among the continuous 1 signals. Therefore, the adjoint sequence is passed through a FIR low-pass filter, which is designed to have an impulse response as follows
Figure 682429DEST_PATH_IMAGE056
And (5) designing. The value range of alpha is (0.9, 1), 0.99 is recommended, the selection of k is related to the period of a typical pulse, the value range can be (10, 60), 50 is recommended, and the whole pulse is

wherein the content of the first and second substances,

for judging the threshold value, the suggested interval is [0.2,0.5 ]]The value is selected according to the pulse discrimination success rate and the false discrimination rate of non-pulse discrimination as pulse. The smaller the value, the higher the success rate of discrimination but the higher the probability that a non-pulse point is discriminated as a pulse point, and the larger the value, the lower the recognition rate of a pulse but the lower the false discrimination rate that a non-pulse point is discriminated as a pulse point. The system gives a discrimination threshold value
