| Outline of Final Research Achievements |
We have searched for reliable and high efficiency of code division multiple access system without interference (ZCZ - CDMA), which multiple mobile terminals can dynamically construct wireless network flexibly. This includes the design of new bent ZCZ codes whose correlation functions are totally low except the zero correlation zone, the design of a compact matched filter bank (MFB) that can output the correlation between the received signal and all sequences of the ZCZ code, the proposal of a high-speed synchronous acquisition circuit using MFB, and the construction of a block coding method for high-speed transmission applying complex Hadamard transform.
