Abstract
In a signal processing method, an input signal is provided at an input to a receiver. A bandwidth of the receiver is controlled to a predetermined wideband setting. For band in a plurality of frequency bands, the input signal is processed at the receiver with a mixer, an amplifier, and a filter, to generate a first processed signal, and a power spectral density of the processed signal is generated over that frequency band, to provide a frequency domain signal for that frequency band. Based on the frequency domain signals corresponding to each frequency band in the plurality of frequency bands, a frequency domain representation of the processed signal is reconstructed over a reconstruction band having a bandwidth larger than the predetermined wideband setting. Based on the reconstructed frequency domain representation, a spectral component is identified corresponding to at least one cellular telephony access mode.
