Abstract: A miniaturized directional antenna for use with system to provide data communication over wireless radio channels. The unit supports multiple antenna elements with a known orientation with respect to an earth ground plane reference. This greatly provides predictability in the steerability and other directional attributes of the antenna array using miniaturized chip multilayer or helical antenna elements, the unit may be constructed in a case or other form factor of approximately 3×3×1 inches for operation within the frequency bands around 1900 MHz.

Abstract: A transmitter which includes a quadrature phase shift keying (QPSK) modulator, and a receiver which includes a pilot correlation filter (PCF), a data matching filter (DMF), a timing recovery mechanism, a sampler, and a QPSK demodulator are provided in a wireless communication system. The transmitter transmits a frame of data symbols and pilot symbols to a receiver in a wireless system. The pilot symbols are inserted in the frame at known time intervals. The QPSK modulator modulates the frame of data and pilot symbols. As the receiver receives the frame of data and pilot symbols from the transmitter, the PCF recovers the pilot symbols sent by the transmitter, whereas the timing recovery mechanism tracks the timing of the pilot symbols in the frame. The DMF enhances the multipath response of the frame of data and pilot symbols at the known time intervals of the pilot symbols, and outputs a plurality of enhanced peaks. The sampler samples the multipath response of the frame of data and pilot symbols at each of the enhanced peaks. The QPSK demodulator demodulates the sampled frame of data and pilot symbols and recovers the data symbols using QPSK demodulation based on the sampled frame.
