A noise estimation algorithm is proposed for highly non- stationary noise environments. The noise estimate is updated by averaging the noisy speech power spectrum using a time and frequency dependent smoothing factor, which is adjusted based on sign
Little Known Characteristics of Phase Noise 为你揭开相位噪声的神秘面纱 INTRODUCTION There is a wealth of information available on the topic of phase noise, its characteristics1, how it can be measured2, and how it affects system performance3. It is well known th
ABSTRACT The problem of matching measured latitude/longitude points to roads is becoming increasingly important. This paper describes a novel, principled map matching algorithm that uses a Hidden Markov Model (HMM) to find the most likely road route
