| Abstract | The Universal Mobile Telecommunications System (UMTS) being specified by the Third Generation Partnership Project (3GPP) and based upon wideband code division multiple access (WCDMA) consists of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. In the UMTS Terrestrial Radio Access (UTRA) TDD mode, the system capacity is maximized with base stations (Node Bs) in a UTRA TDD mode deployment area operating synchronously. A Node B synchronization mechanism based upon transmissions and timing measurements of synchronization bursts between neighboring Node Bs has been specified as part of release 2000 (now called release 4) in 3GPP. A family of new synchronization codes, so-called concatenated extended complementary (CEC) sequences have been chosen for the Node B synchronization bursts. The CEC sequences are derived from polyphase complementary pairs which facilitate the use of efficient and low-complexity receiver implementations. The CEC sequences have perfect aperiodic auto-correlation properties within a window of adjustable size and excellent overall autocorrelation properties. This paper describes how to derive the CEC sequences and their auto-correlation properties and details the design of the CEC sequences adapted to the inter-base station synchronization over the air process. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
