The
mobile robot has to find the optimal path which reduces the number of steps to be taken between the
starting point and the target ending point. GAs can overcome many problems encountered by
traditional search techniques such as the gradient based methods. The proposed controlling algorithm
allows four-neighbor movements, so that path-planning can adapt with complicated search spaces with

传统的短时谱估计语音增强算法通常假设语音谱分量相互独立,没有考虑语音谱分量间的相关性。针对这
一问题,该文提出一种新的基于多元Laplace分布模型的短时谱估计算法。首先,假设语音的离散余弦变换(DCT)
系数服从多元Laplace分布,以此利用谱分量间的相关性;在此基础上,利用多元随机矢量的高斯尺度混合模型表
示,推导得到语音DCT系数矢量的最小均方误差(MMSE)估计的解析表达式;并进一步推导了基于该分布模型的
语音存在概率,对最小均方误差估计子进行修正。实验结果表明,该算法在抑制背景噪声和减少语音失真等方面优
于传统的语音增强方法。(The spectral components of speech are usually assumed to be independent in traditional short-time
spectrum estimation, which is not the case in practice. Tosolve this problem, a new speech enhancement algorithm
with multivariate Laplace speech model is proposed in this paper. Firstly, the speech Discrete Cosine Transform
(DCT) coefficients are modeled by a multivariate Laplace distribution, so the correlations between speech spectral
components can be exploited. And then a Minimum-Mean-Square-Error (MMSE) estimator based on the proposed
model is derived using a Gaussian scale mixture representation of random vectors. Furthermore, the speech
presence uncertainty with the new model is derived to modify the MMSE estimator. Experimental results show
that the developed method has better noise suppression performance and lower speech distortion compared to the
traditional speech enhancement method. )

we address the design of economical
recursive generalized comb filters (GCFs) by proposing an ef-
ficient technique to quantize the multipliers in the z-transfer
function employing power-of-2 (PO2) terms. GCFs are efficient
anti-aliasing decimation filters with improved selectivity and
quantization noise rejection performance around the so-called
folding bands with respect to classical comb filters. The proposed
quantization technique guarantees perfect pole–zero cancelation
in the rational z-transfer function of the GCFs, thus totally
avoiding instability problems. Moreover, we propose the use of a
simple droop compensator for the sake of recovering the passband
droop distorting the useful digital signal in the baseband. A design
example is proposed with the aim of showing the application of
the proposed technique, and a practical architecture of a sample
third-order GCF is discussed.
