摘要： A zoom lens barrel comprises an exterior unit, which mainly forms an exterior portion, an optical unit having an image pickup optical system built therein, and a control unit and can be detachably mounted on a single-lens reflex camera. The optical unit includes first and second group lenses as the image pickup optical system, which can move forward and rearward in zooming and focusing, and a third group lens which can move forward and rearward in zooming. Particularly, in focusing, a first group lens holding frame for holding the first group lens and a second group lens holding frame for holding the second group lens are driven forward and rearward in a different amount in an optical axis direction through a cam follower and two cam grooves by driving a focus ring in rotation, thereby focusing is executed. The lens barrel can cope with a forward/rearward movement required in zooming and focusing and can be reduced in size.

摘要： A MC-CDMA handset has a receiver (30) that estimates SIR based on a spread factor of a pilot channel. More particularly, a spread spectrum signal including a pilot channel and multiple data channels is received. The pilot channel is despread using a spread factor (SF). The SIR for the despread pilot channel is calculated and stored in a memory (34). The SF is then incremented and used to despread the pilot channel again, and this process is repeated for all of SF. The stored SIRs are compared to a threshold value in ascending order of the SFs. The first SIR value to fall below the threshold value is used as the estimated SIR result.

摘要： Reference sequences are constructed from distinct “classes” of GCL sequences that have an optimal cyclic cross correlation property. The fast cell search method disclosed detects the “class indices” with simple processing. In a system deployment that uniquely maps sequences of certain class indices along with a circular shift amount in time domain to certain cells/cell IDs, the identification of a sequence index, and its circular shift will therefore provide an identification of the cell ID.
摘要翻译：参考序列由具有最佳循环互相关性质的GCL序列的不同“类别”构成。所公开的快速小区搜索方法通过简单的处理来检测“类索引”。在将特定类索引的序列以及时域中的循环移位量唯一地映射到某些小区/小区ID的系统部署中，因此序列索引的识别及其循环移位将提供小区ID的标识。
