Signaling and Data Transmission in a Digital Cellular System
01 January 1989
The introduction of digital cellular systems in the United States will bring with it the opportunity for data transmission over the mobile channel. Digital transmission will also bring different options for signaling. The cellular channel presents some very difficult challenges to the transmission of digital data. This paper examines the performance of data transmission at 4800 b/s and 9600 b/s in a single time slot of a TDMA channel. Data block-error rates are presented with different coding rates and interleaving depths. The effects of interleaving and diversity are discussed. It is found that interleaving can provide a significant performance improvement when the proper interleaving depth is used. Several options for signaling are also presented.
