A communication device, comprising: a first transceiving means for transmitting a first communication signal of a first communication protocol; a second transceiving means for receiving a second communication signal of a second communication protocol; and a controlling means configured to: identify a first communication channel of the first communication signal; identify a second communication channel of the second communication signal; calculate a frequency spacing between the first and second communication signals; determine a bandwidth of the first communication channel; calculate a rate of change over frequency of a power spectral density, PSD, of the first communication signal based on the bandwidth of the first communication channel; calculate one or more PSD decay over frequency terms of the first communication signal based on the rate of change of the PSD over frequency of the first communication signal and the frequency spacing; compare the one or more PSD decay terms to a noise level of the first communication signal; calculate one or more interference power integration terms, representing the larger of the PSD decay and the noise level of the first communication signal within a bandwidth of the second communication channel, based on the one or more PSD decay over frequency terms and on the comparison; calculate a maximum of the one or more interference power integration terms; calculate one or more power delta terms as a difference between the one or more interference power integration terms and the maximum of the one or more interference power integration terms; and estimate the interference of the first communication signal on the second communication signal in the second communication channel based on the maximum of the one or more interference power integration terms and individual factors determined from the one or more power delta terms, where the individual factors are stored in a look-up-table. a first transceiving means for transmitting a first communication signal of a first communication protocol;
