Turbo code becomes popular for the next generation wireless communication systems because of its remarkable coding performance. One of the problems for decoding turbo code in the receiver is the complexity and the high power consumption since multiple iterations of Soft Output Viterbi Algorithm (SOVA) have to be carried out to decode a data frame.

BACKGROUND Despite the increasingly ageing population, teaching geriatric medicine at medical schools is a challenge due to the particularities of this subspecialty and the lack of student interest in this subject. METHODS We assessed a blended system that combines e-learning and person-to-person interaction. Our program offered the students a hands-on(More)
| In this w ork, an implementation of a time-multiplexed downlink Rake receiv er complied with the IS-95 CDMA standard is presented. A l o w p o w er arc hitecture of the Rake receiver is implemented. A structure which provides the ooset changing for the pseudo-random sequence (PN sequence) used for despreading of the CDMA signals is discussed. Arc(More)
The motor recovery procedure of chronic stroke during robot-assisted training has not been well studied previously. In this work, we analyzed the variations in the coactivating patterns of elbow and shoulder muscles (biceps, triceps lateral, anterior deltoid, and posterior deltoid) in hemiplegic persons with chronic stroke (n=4) during a 20-session's(More)
OBJECTIVE. To evaluate results from surgical release of trigger thumbs in children in a regional hospital cluster in Hong Kong. DESIGN. Descriptive case series. SETTING. A regional hospital cluster, Hong Kong. PATIENTS. Data from 1993 to 2009 on 180 children with 209 trigger thumbs were collected. Analyses into gender, predominance of thumb, age of onset,(More)
BACKGROUND The optimal reference range of homeostasis model assessment of insulin resistance (HOMA-IR) in normal Chinese population has not been clearly defined. Here we address this issue using the Hong Kong Cardiovascular Risk Factor Prevalence Study (CRISPS), a prospective population-based cohort study with long-term follow-up. MATERIAL & METHODS In(More)
