K. Ohuchi et H. Habuchi, AN ANALYSIS OF FRAME SYNCHRONIZATION SYSTEMS WITH RACING COUNTERS ANDMAJORITY-RULE FOR M-ARY SS COMMUNICATION-SYSTEMS/, IEICE transactions on fundamentals of electronics, communications and computer science, E80A(12), 1997, pp. 2406-2412
In this paper, a simple frame synchronization system for M-ary Spread
Spectrum (M-ary/SS) communication systems is analyzed, In particular,
synchronization performance, bit error rate performance, and Spread Sp
ectrum Multiple Access (SSMA) performance are analyzed. The frame sync
hronization system uses the racing counters. The transmitted signal co
ntains framing chips that are added to spreading sequences. In the rec
eiver, the framing chips are detected from several frames. The authors
have proposed the simple Frame synchronization system that detects fr
aming chips from consecutive 2 frames. In this system, as the number o
f framing chips increases, synchronization performance improves and bi
t error rate performance degrades. In this paper a frame synchronizati
on system that improves bit error rate performance is treated and anal
yzed. As the result, when the number of reference frames is 3, the bit
error rate is much improved than the conventional system.
