    Abstract

    Measurements made on a direct-sequence spread-spectrum radio using differential phase-shift keying modulation for a wireless PBX are reported. The design and implementation of a transmitter and a receiver using a surface acoustic wave (SAW) filter matching the spread-spectrum code of a user are described. Receiver performance in a multipath fading indoor environment with multipath fade notches of up to 50-dB depth is shown. Multiple access capability provided by introducing an interfering transmitter with a different spread-spectrum code sequence is investigated.
