Abstract
AbstractVirtual time reversal mirror can effectively suppress intersymbol interference caused by multi-path effects caused by the Multi-path effect In underwater acoustic communication. Digital virtual time reversal mirror is optimal implementation of traditional virtual time reversal mirror. It only need to store Amplitude information and Delay information of the point which amplitude is not zero in the Estimated channel impulse response and it only do limited multiply-accumulate operations to received signal in the process of time reversal convolution. Thus, digital of virtual time reversal mirror saves DSP storage space, at the same time, it will aslo significantly reduce the computational. In this paper, we do simulation experiments of digital of virtual time reversal mirror on the Da Vinci platform, verifies that digital of virtual time reversal mirror can effectively suppress multi-path effects caused by ISI and it is feasible in engineering applications.Keywordsunderwater acoustic communicationvirtual time reversal mirrordigitalDa Vinci platform
