Abstract


Ultra-wideband communication technology is an emerging short-range wireless communications technology, which uses a non-sine wave pulse transmit data with a high transfer rate, low power consumption, security, anti-multipath ability nanosecond to picosecond and cost many advantages, it does not need to take up additional spectrum resources, this characteristic can be used with existing wireless communication system to coexist in the same band, it received extensive attention in the the spectrum resources increasingly tense today. At present, ultra-wideband communications technology has become one of the hotspots of the wireless communication technology. Rake receiver multipath channel and multi-user interference in these two areas to study ultra wideband communication system based on the the truncated balance of Gold code and get some meaningful results, the main work is summarized as follows: 1. Analysis truncated balanced Gold code generation principle, given the truncated balanced Gold code generation method, and to verify the feasibility of the method. The ultra-wideband channel model, and discuss general modeling process for ultra-wideband wireless communication channel model. Highlights SV channel model and Intel channel model and the Intel channel model simulation analysis, a summary analysis of the propagation characteristics of ultra-wideband wireless channel. Given multipath channel Rake receiver transmitting end and the receiving end of the model, with the truncated balance Gold code instead of the traditional time-hopping code analyzed in the pulse position modulation (PPM), and pulse amplitude modulation (PAM) the the ideal modulation mode receiver (A-Rake), Rake receiver (P-Rake) and selective Rake receiver (S-Rake) three Rake receiver mode error performance and simulation. Simulation results show that in the case of multi-path channel, the BER performance of the truncated code is superior to the traditional code BER performance; PAM modulation scheme under the same conditions, the BER performance of the receiver is better than using a PPM modulation error performance. Detailed analysis of ultra-wideband communication system under multi-user interference principle, the establishment of a multi-user interference model of ultra-wideband communication system. PPM and PAM two different modulation methods, the ultra-wideband communication system by the number of different user interference error performance analysis, simulation experiments show that: in the case of multi-user interference, using the same modulation scheme, the use of The truncated code BER performance of a communication system to be better than the BER performance of the conventional communication system.
