Abstract
A field trial was conducted which demonstrated that compressed video and wireline quality audio at 64 kbps could be transmitted using the existing cellular telephone spectrum (825-894 MHz) without affecting the normal cellular service. The technology employed was broadband code division multiple access (B-CDMA) augmented with programmable digital notch filters. This paper describes the B-CDMA and digital filter techniques, the cellular overlay concept, and projected performance based on Monte-Carlo simulations. Lastly, the field demonstrations conducted with US Cellular in Des Moines, Iowa, are described.
