    摘要: A reconfigurable multichannel receiver may selectively operate in increased throughput 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: Embodiments of millimeter-wave transceivers with coarse and fine beam steering with interference suppression are generally described herein. In some embodiments, a millimeter-wave transceiver configured for multipath reception of multicarrier signals and includes RF circuitry to receive multicarrier signals through at least two independently controllable sub-arrays from first and second directions, a channel-estimation block to generate a set of weighting coefficients for each sub-array based on channel characteristics determined from each sub-array, the weighting coefficients generated for inter-channel interference (ICI) suppression, and maximum-ratio combining (MRC) circuitry to apply a set of the weighting coefficients to baseband signals from each sub-array and to combine the weighted baseband signals from each sub-array to generate combined baseband signals that represent a single data stream.

    摘要: Embodiments of a millimeter-wave (mmW) communication device and methods for intelligent control of transmit power and power density are generally described herein. In some embodiments, a mmW base station includes a beamforming processor that is to configure a large-aperture array antenna for multi-beam transmissions at mmW frequencies to a plurality of user equipment (UE). The beamforming processor may allocate each UE a non-interfering spectral portion of a full channel bandwidth that is substantially less than the full channel bandwidth and perform multi-beam beamforming to concurrently direct a plurality of multi-user multiple-input multiple-output (MU-MIMO) antenna beams to the UEs for a concurrent transmission of data streams to the UEs within their allocated spectral portion in accordance with a transmit power allocation.
