Novel UWB-IR communication system based on chaotic pulse position modulation

Since proposed CPPM UWB-IR communication systems have poor performance of BER, a novel demodulation method was presented, which could evidently improve the BER performance by using a slipping window to control the working period of the matched filter. Another method which came from parameter sensitivity was also introduced to realize initial synchronization of this system. Simulations show that the BER performance of this novel system can be improved by 7~8 dB, which verifies the validity of this scheme.
