A comparsion of binary paging codes

Abstract

A comparison of two of the major coding formats for binary paging is presented. Performance of the codes is investigated for both Gaussian noise and Rayleigh fading. An analytical analysis of the stationary pager in a fading field is also presented. For the Gaussian and Rayleigh fading cases, the testing uses a common radio and bit detector as the receiver with either frontend noise or a Rayleigh Fading simulator to simulate the rf channel. A minicomputer is interfaced to both the rf generator and the data output of the bit detector and serves as the source, sink and statistics tabulator for the testing. In addition to alert-only paging, this study investigates the performance of both numeric and alphanumeric paging. A discussion of the implications of the various sensitivity differences is included.
