1. A millimeter-wave transceiver configured for multipath reception of multicarrier signals comprising: RF circuitry to receive the multicarrier signals through at least two independently controllable sub-array antennas from first and second directions, the first direction being associated with received signals of a highest signal level and the second direction being associated with received signals of a next highest signal level; a channel-estimation block to generate a set of weighting coefficients for each sub-array antenna based on channel characteristics determined from each sub-array antenna, the weighting coefficients generated for inter-channel interference (ICI) suppression; and maximum-ratio combining (MRC) circuitry to apply the set of the weighting coefficients to baseband signals from each sub-array antenna and to combine the weighted baseband signals from each sub-array antenna to generate combined baseband signals that represent a single data stream.
