For future information technology, the efficiency of the wireless frequency usage is very important. In the current technology, the most serious problem for wireless communication is the multipath problem. We have proposed a very efficient frequency usage system based on multipath estimation and spread time signals based on the signal design of zero correlation zone (ZCZ) signals using complete complementary codes. In this paper,the new zero cross-correlation zone (ZCCZ) signals proposed by us is applied on the method. The system uses the pilot signal or measuring the multipath properties as the complex time delay, and the data transmission signals. The pilot signal and the data transmission signals can be used independently in the same time and the same frequency band without crosscorrelating nor interference. The system can get the current multipath properties and use them to detect the transmitted data by adding the multipath signal coherently.
