1. A method of detecting impulsive noise in a stream of sets of signal samples in a radio receiver, wherein each of said sets comprises at least one of said samples, said method comprising the steps of:

  • (a) comparing a value based on an amplitude of said at least one sample of each said set with each of a number J of thresholds Tj, where J is greater than zero;

    (b) determining each number nj of said sets in each Nj consecutive ones of said sets for which said value is greater than Tj for each value of j such that 1≦

    j≦

    J; and

    (c) indicating a noise impulse when each said number nj is greater than a respective first number Xj.
