Channel Selection Filter Compensation

A method of a communication device adapted to process a received signal using either of a first channel selection filter and a second channel selection filter, each channel selection filter having a respective filter function and a respective pass band, the received signal comprising signal entities each representing an individually processed block of data, the method comprising:

• during use of the first channel selection filter, detecting a presence of an interference signal outside of the pass band of the first channel selection filter;
• switching to use of the second channel selection filter in response to detecting the presence of the interference signal;
• and
• if the switching occurs at a first point in time within a first signal entity dividing the first signal entity into a first part and a second part, applying a time domain compensation filter to one of the first part and the second part of the first signal entity, the time domain compensation filter having a filter function.

A non-transitory computer readable recording medium storing a computer program product for controlling a communication device adapted to process a received signal using either of a first channel selection filter and a second channel selection filter, each channel selection filter having a filter function and a pass band, the received signal comprising signal entities each representing an individually processed block of data, the computer program product comprising software instructions which, when run on processing circuitry of the communication device, causes the communication device to:

• during use of the first channel selection filter, detect a presence of an interference signal outside of the pass band of the first channel selection filter;
• switch to use of the second channel selection filter in response to detecting the presence of the interference signal;
• and
• if the switching occurs at a first point in time within a first signal entity dividing the first signal entity into a first part and a second part, apply a time domain compensation filter to one of the first part and the second part of the first signal entity, the time domain compensation filter having a filter function.

A receiver arrangement of a communication device adapted to process a received signal using either of a first channel selection filter and a second channel selection filter, each channel selection filter having a respective filter function and a respective pass band, the received signal comprising signal entities each representing an individually processed block of data, the receiver arrangement comprising:

• the first channel selection filter;
• the second channel selection filter;
• a time domain compensation filter having a filter function;
• and
• a control circuit configured to:
• during use of the first channel selection filter, detect a presence of an interference signal outside of the pass band of the first channel selection filter;
• switch to use of the second channel selection filter in response to detecting the presence of the interference signal;
• and
• if the switching occurs at a first point in time within a first signal entity dividing the first signal entity into a first part and a second part, cause application of the time domain compensation filter to one of the first part and the second part of the first signal entity.
