Methods, Devices and Systems for Processing a Signal in the Presence of Narrowband Interference

A computer program product comprising a computer readable medium, having stored thereon a computer program comprising program instructions, the computer program being loadable into a data-processing unit and adapted to cause the data-processing unit to execute a method when the computer program is run by the data-processing unit, wherein the method is for processing a received signal in the presence of an interference of a first type within the bandwidth of a desired signal of the received signal, the method comprising:

• filtering the received signal using at least a first filter having at least a first filter characteristic to produce a filtered signal, wherein the interference of the first type is suppressed;
• and
• determining a desired data stream from the filtered signal,
• wherein the step of determining the desired data stream from the filtered signal comprises basing the determination at least on the first filter characteristic.

A receiver for processing a received signal in the presence of an interference of a first type within the bandwidth of a desired signal of the received signal comprising:

• at least a first filter having at least a first filter characteristic and adapted to filter the received signal to produce a filtered signal and to suppress the interference of the first type;
• and
• a detector adapted to determine a desired data stream from the filtered signal,
• wherein the detector is adapted to determine a desired data stream from the filtered signal based at least on the first filter characteristic.
