Paper Abstract

Based on spread spectrum signals detecting technology, a kind ofsoftware capture method ofspread spectrum signals is presented. in this paper. A kind of 2-D signal capturing method is advanced which combines parallel pseudorandom-code (PN-code) phase and capturing of carrier frequency, as a result, the capturing time is shortened greatly. The method is used in this system by which the energy is accumulated to improve the signal-to-noise ratio (SNR) ofinput-signals, consequently improve the detection performance. The working principle and overall structure of the capturing system is introduced. The capturing structure model and mathematical one, the acquisition algorithm and realization, the design of parameters are discussed in detail. The possibility of the system has been verified by experiments and performance analysis.
