Study on the auto-correlation and cross-correlation properties of hybrid bridge function sequence

The sequences a communication system selected affect the performance of the system, so the paper focuses on the study on the correlation properties of a special sequence called hybrid bridge function sequence. Some basic concepts and classification of hybrid bridge function are presented in the paper, and the properties of hybrid bridge function sequences and their superiorities and disadvantages are presented through theoretical analysis and simulations. Finally, it can be seen that hybrid bridge function sequence is just like a bridge between bridge function sequence and Walsh sequence, so the conclusion that the hybrid bridge function's properties are superior to Walsh sequence's but worse than bridge function sequence's can be obtained through the comparison of the simulation results of the communication system.
