Abstract: A multi-mode transmission system supporting OFDM and single-carrier signals is configured to perform interpolation and decimation such that the ratio of the interpolation factor to the decimation factor equals the ratio between the OFDM sampling rate and the single-carrier chip rate. A constant-envelope modulator comprises a π/4 fixed rotator, a π/2 continuous rotator, and in-phase and quadrature-phase analog Bessel filters. Frame formats and signaling protocols are provided for signal acquisition, synchronization, and tracking between wireless devices that employ different antenna configurations. Spreading gains are selected to compensate for different antenna gains such that the total gain (antenna gain plus spreading gain) is substantially equal for transmissions employing different beam patterns.

Abstract: In a millimeter-wave radar, full-duplex operation comprises identifying a leakage signal in a digital baseband received signal, estimating the leakage signal, synthesizing an estimated leakage signal, and subtracting the estimated leakage signal from the digital baseband received signal. The time interval during which the leakage signal occurs may be measured, and samples of the digital baseband received signal within the time interval are masked to remove the leakage.

Abstract: A method of communication includes allocating a portion of a superframe centralized contention based period where the access method is based on directional ALOHA. The centralized contention based period is divided into equal time slots, and each sequential set of N time slots forms a time cycle. During a time cycle, a wireless device listens for requests from other wireless devices while it changes its receiving direction from one time slot to another.

Abstract: A beamforming method comprises transmitting a training sequence from a transmitter array employing a set of beamforming vectors from a beamforming codebook. A receive array employs a combining codebook to acquire channel state information from the received transmissions, and estimates a preferred beamforming vector and a preferred combining vector. At least the preferred beamforming vector (and, optionally, the preferred combining vector) is transmitted back to the transmitter array.
