PERFORMANCE OF A TDMA PORTABLE RADIO SYSTEM USING A CYCLIC BLOCK CODEFOR BURST SYNCHRONIZATION AND ERROR-DETECTION

In this paper, a combined burst synchronization and error detection sc heme is studied for a TDMA portable radio system. Analysis, computer s imulation and experimental results of the false acceptance rate of the system using the combined scheme are presented. It is found that for a (161,147) code used in this study, which is capable of correcting +/ -6 b sync slippage, the error detection capability of the code is degr aded by 3 b on a slow Rayleigh-fading channel using coherent QPSK demo dulation with differential decoding. However, lower implementation com plexity and higher efficiency are obtained than with separate burst sy nchronization and error detection processes.
