Wideband Spread Spectrum Modulation for Higher-Data-Rate Mobile Communications

This paper describes some results of study on spread spectrum modulation method for higher-data-rate transmission. This scheme is expected useful against multipath radio propagation in urban mobile radio communication. Characteristics of wideband spreading were first evaluated. A novel configuration with matched filters is described for efficient and reliable synchronization under multipath environment. A prototype hardware was fabricated with new configuration. Expected system capability was lastly estimated based on system size and data rate. Mobile radio communications are now major in public communications.
