This study proposes an improved delay-and-sum algorithm (DSA) considering EM wave refraction in planar multi-layered media. The proposed DSA overcomes the limitations of existing methods by addressing both the constraints of two-layer cases and the reliance on propagation path approximations, thus ...
从每一个来看,grating lobe就是栅瓣: 二、Delay and sum DSB核心的思想就是延迟相加,对于栅瓣的DOA估计需要解模糊。假设估计出DOA,进行补偿之后(delay)通过叠加(sum)就可以实现目标信号的增强: 关于delay的操作,可以在时域进行也可以在频域进行,本质上是小数延迟的问题(fractional delays).例如对于下面的dual-channel...

这篇文章主要有两点特色: 1)在Frost’s algorithm基础上,进行了理论扩展; 2)论述了基于麦克风阵列的GSC框架. 一、理论回顾 假设噪声为加性: 其中s是desired signal,n 是noise.m为第m个麦克风,m∈[1 双麦克风语音增强之ANF 自适应零点形成 概述ANF(Adaptive Null-Forming,自适应零点形成)是双麦克风阵列处理中...
Echo state networks (ESNs) are a novel approach to recurrent neural network training with the advantage of a very simple and linear learning algorithm. It has been demonstrated that ESNs outperform other methods on a number of benchmark tasks. Although the approach is appealing, there are still...
(1998) analyzed the problem of adaptively adjusting the playout delay in order to keep this delay as small as possible to avoid excessive losses and proposed the adaptive delay adjustment algorithm that tracked the network delay of recently received packets and efficiently maintained delay percentile ...
是先随便假设一个,然后通过不断反馈和迭代得到的,现在假设当前的系统的一个概率分布,然后现在A发生了,那么基于当前的概率分布预测到了B发生的概率是50%,但实际上观察到了B发生概率是60%,说明我们当前的概率分布模型有问题(也就是均值和方差有问题),那就让当前的概率模型朝着这个方向去收敛,经过不断迭代之后慢慢...

We also estimate the probability mass function (pmf) of the MAC delay through the lattice Poisson algorithm. As far as the queuing delay is concerned, we provide the mean queuing delay by considering a queuing system with one queue per Access Category (AC) per mobile station, with a single...
