Abstract:
1. A method of operating a radio-receiver circuit, wherein the radio-receiver circuit comprises an analog-to-digital conversion unit comprising an analog-to-digital converter, ADC, and a filter operatively connected to an input terminal of the ADC in a receive path of the radio-receiver circuit, the method comprising the steps of: receiving control data; determining, based on the control data, a frequency band in which data is to be transmitted to the radio-receiver circuit during a subsequent time interval; and, adapting at least one frequency characteristic of the analog-to-digital conversion unit to the determined frequency band for receiving said data transmitted in said subsequent time interval; wherein the radio-receiver circuit is adapted to receive data over an orthogonal frequency-division multiplexing (OFDM) communication channel, the control data is comprised of one or more initial OFDM symbols of a sequence of consecutive OFDM symbols, the subsequent time interval is a time interval corresponding to one of the OFDM symbols of the sequence of consecutive OFDM symbols that follow after said one or more initial OFDM symbols, and the frequency band in which data is to be transmitted to the radio receiver circuit is a frequency band within the OFDM symbol.
