摘要： A reconfigurable multichannel receiver may selectively operate in increased throughout modes and/or increased range modes. In some embodiments, the receiver may select two or more antennas from a plurality of spatially diverse antennas to receive more than one subchannel of a wideband orthogonal frequency division multiplexed (OFDM) channel. Maximum-ratio combining may be performed on corresponding symbol-modulated subcarriers from the two or more antennas, and a single OFDM symbol may be generated from contributions from the subchannels received by the two or more antennas. In other embodiments, more than one subchannel of a wideband OFDM channel may be received through a single antenna selected from a plurality of spatially diverse antennas. In other embodiments, a single subchannel may be received by a plurality of spatially diverse antennas and maximum-ratio combining may be performed on corresponding symbol-modulated subcarriers received by the antennas.

摘要： A quasi-parallel receiver may simultaneously receive signals within several subchannels that comprise a wideband channel. The receiver includes a subchannel filter selection switch that provides a baseband signal to a selected one of a plurality of subchannel low-pass filters. A heterodyne frequency generator provides one of a plurality of heterodyne frequencies to convert an RF signal received within a selected subchannel to the baseband signal. The subchannel low-pass filters accumulate signal information from an associated one of a plurality of subchannels during a filter-input sampling interval. In some embodiments, individual analog-to-digital converters receive the accumulated signal outputs from an associated subchannel filter and generate digital signals for a subsequent Fourier transformation. In some embodiments, a normalized signal output may be provided to the analog-to-digital converters, allowing the use of lower resolution analog-to-digital converters. The analog-to-digital converters may have sampling rates based on the subchannel bandwidth.

摘要： Communication signals using a first and a second frequency band in a wireless network is described herein. The first frequency band may be associated with a first beamwidth while the second frequency band may be associated with a second beamwidth, the first beamwidth being wider than the second beamwidth. The first frequency band may be used to communicate first signals to facilitate initial communication, including signals and/or control information to coarsely configure a receiving device. The second frequency band may then be used to communicate second signals that facilitate further communication, including signals and/or control information for finer configuring of the receiving device. Alternatively, the first and second frequency bands may be used in a wireless network to communicate a first and a second signals independently.

摘要： In a multiple-input multiple-output (MIMO) multicarrier communication system, a mobile station sends a quantized time-domain representation of the channel transfer function to a base station for use by the base station in generating beamforming coefficients for use in subsequent transmissions to the mobile station. In some embodiments, the quantized time-domain representation of the channel transfer function may be generated from selected most significant rays of an initial estimated sampled channel impulse response. Other embodiments may be described and claimed.
