Abstract
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.
