Abstract
A modem apparatus is configured to provide wireless network access in accordance with an Orthogonal Frequency Division Multiplexing communications scheme. The apparatus comprises a hardware subsystem comprising baseband processing components (), Radio Frequency processing components () and a digital interface. The Radio Frequency processing components () comprise a converter component arranged to convert between time and frequency domains in accordance with the Orthogonal Frequency Division Multiplexing communications scheme; a subcarrier processing component operably coupled to the converter component, the subcarrier processing component being arranged to implement conversion between a collapsed space of subcarriers and an expanded space of subcarriers in accordance with resource assignment data; a cyclic prefix processing component responsive to control information. The baseband processing components () comprise a channel estimation component. The digital interface () is disposed between the baseband processing components () and the RF processing components (), the digital interface () being operably coupled to the subcarrier processing component and the channel estimation component.
