BIT ERROR RATE OF BIORTHOGONAL SYSTEMS CONSIDERING SYNCHRONIZATION PERFORMANCE

In this paper, the bit error rate (BER) considering tracking performan ce is evaluated, by theoretical analysis and computer simulation, for a bi-orthogonal system using a synchronizing pseudo-noise (PN) sequenc e and cochannel interference cancellers. A system that improves on Tac hikawa's system is proposed. It is found that the optimum ratio of the information signal energy to the synchronizing signal energy varies w ith E(b)/N-0, and the canceller is better for small L than for large L (L = length of the sequence). Moreover, it is Found that the BER cons idering synchronization performance improves as the equivalent noise b andwidth B-n decreases.
