Simulation and Analysis of Underwater Acoustic Spread Spectrum System Based on LabView
Anti-jamming, concealment and low signal noise ratio detection of direct sequence spread spectrum system is much better than regular communication system. Under typical three paths acoustic channels, LabView-based simulations of direct sequence spread spectrum were carried out. Through the combination of LabView and Matlab, the spread spectrum synchronous, decision feedback equalizer and RAKE receiver were used in the spread spectrum systems. The simulation results show that the multi-path interference has been overcomed effectively. And correctness of theoretical analysis was confirmed furthermore, which would give certain reference to analysis and design of the practical system.
