N -continuous OFDM is a modulation technique that has a lower sidelobe than the original OFDM as a result of the continuous connection with its higher-order derivatives between the OFDM symbols. However, N -continuous OFDM has a high symbol error rate. In the present paper, we improve N -continuous OFDM without increasing the symbol error rate by using a selected mapping technique.
This study investigated the effects of High Variability Phonetic Training (HVPT) in training both the perception and production of English highfront vowels /ɪ/-/iː/ and high-back vowels /ʊ/-/uː/ by Cantonese ESL learners. Results showed that the HVPT was generally effective in improving the subjects’ perception of the two vowel pairs and perceptual learning could generalize to new words and new...
Engineering—Mechanical) Three-dimensional Holographic Lithography and Manipulation Using a Spatial Light Modulator by
The applicability of Flege’s Speech Learning Model (SLM) to simultaneous bilinguals is examined in related experiments on the acquisition of the production and perception of the voicing contrast in simultaneous French-English bilinguals. The results show that the SLM can account for the data providing account is taken of the degree of bilinguals’ exposure to each language.
The performance and operation of high-speed, liquid crystal spatial light modulators are discussed in relation to a variety of system-level aspects. The issues involving the use of these devices in optical processing systems are the primary focus of this paper, but other applications such as ultra-video imaging and beamsteering are also included in the discussion.
