Description: This project aim was to build wireless software modem for data communication
between two computers using an acoustic interface in the voice frequency range (20Hz–
20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz –
20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz –
16,000Hz). The test files used as information files were text files.
This goal was attained both in an incoherent scheme and in a coherent scheme.
Build under Matlab code, our modem uses OFDM (orthogonal frequency division
multiplexing) modulation, synchronization by LMS sequence, channel estimation (no
equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of
2 or 4. To optimize the probability of error, these symbols were mapped using Gray
mapping.

Description: 使用非线性动力学中的一维和二维耦合格子模型研究两个声光双稳系统的时空混沌同步.将驱动系统的输出以适当的比例耦合到响应系统并进行均衡 , 能实现两系统的时空混沌同步.利用计算最大条件Lyapunov指数 , 给出达到同步所需的最小耦合强度与系统参数的关系. 数值实验表明 ,在小噪声影响时仍然可以实现两系统的同步 , 此法具有一定的抗干扰能力.-The use of nonlinear dynamics of one-dimensional and two-dimensional lattice model of coupled two acousto-optic bistable system of space-time chaos synchronization. Will drive the output coupling ratio appropriate to the response system and a balanced, able to realize the two systems spatiotemporal chaos synchronization. the use of calculating the maximum Lyapunov index, given the minimum required to achieve synchronous coupling strength and system parameters. Numerical experiments show that the effect of small noise can still realize the synchronization of two systems, this method has certain anti- interference.
