Systems and methods are provided for sending and receiving information over different bandwidths, using a shared baseband processor. The transmission method selects clock sampling frequencies, for example a first clock frequency ( l x F1), or a second clock frequency ( k x F1), where k > l . Digital information is processed using the selected clock sampling frequency and a baseband signal is generated. Regardless of the clock sampling frequency selected, the baseband signal may have the same number of subcarrier frequencies. The baseband signal is converted into a radio frequency (RF) signal having a data rate responsive to a selected clock frequency, and transmitted. More explicitly, a first baseband signal is generated having a first data rate in response to selecting the first clock frequency. A second baseband signal having a second data rate greater than the first data rate, may be generated in response to selecting the second clock frequency.
