Abstract
Embodiments are disclosed for extracting sub-bands of interest from signals in a frequency domain for transmission via a distributed antenna system. In one aspect, a transformed downlink signal is generated by performing a frequency transform on a downlink signal. The transformed downlink signal represents the downlink signal in a frequency domain. At least one sub-band of the transformed downlink signal is identified as including data to be transmitted via the distributed antenna system. The sub-band is extracted from the transformed downlink signal for transmission via the distributed antenna system.
