A Universal Ultrawideband Air Interface for Fourth-Generation Communications Based on a Quadrature Analog Surface-Acoustic-Wave Preprocessor

摘要

New possibilities for creating a universal ultrawideband mobile telecommunications system compatible with forth-generation applications and with a stationary wireless ultrahigh-speed local loop are investigated. It is shown that the employment of surface-acoustic-wave technology can appreciably improve the performance of the physical level of the system's air interface.
