摘要： A PPB-CM communication system and method. The PPB-CM communication system includes a transmitter which splits a symbol period, which is a transmission unit of a communication signal, into at least a pair of parts, inserts a data signal into one of the parts, and transmits a communication signal having the data signal inserted; and a receiver which receives the communication signal from the transmitter and determines bit information of the symbol period according to which part of the symbol period has the data signal inserted, as determined by comparison of energy levels of the parts. Accordingly, a separate threshold is not required to determine the data bit of the symbol period. Thus, the communication signal can be accurately determined. Also, the communication system can be simply implemented without need of a delay line.

The analog correlator can perform very high speed data communication, and can be applied to a high precision position estimation system. Moreover, the time delay is controlled in each part of the transmission line by adjusting a size of a variable capacitor. As a result, the length of the transmission line can be adjusted. Furthermore, the correlator is adaptively used according to variations of the very high speed communication environment by adjusting voltages of application voltage devices.
