Abstract
Standards for a new cellular mobile radio system for North America are currently being defined. The system will use digital transmission in contrast to the present analog system. Capacity is increased by means of three techniques. These are: sending three digital voice channels in one current analog FM channel (maintaining spectral compatibility), increased trunking efficiency, and exploiting improved frequency reuse offered by robust digital transmission techniques. The main elements of the system, such as multiple access digital modulation, speech coding, channel coding, and equalization, are briefly discussed. The North American system is compared to the pan-European digital GSM (Groupe Speciale Mobile) system, and techniques that may be used to further improve the system capacity of future digital cellular systems beyond the current standard are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
