نویسنده
چکیده
This study deals with the main characteristics of the Maximal Length, Gold, Kasami, Walsh and variable-length orthogonal codes and their functions in code-division multiple access(CDMA) networks. The important properties of the sequences are examined. A method of multiple spreading for channelization and scrambling in CDMA is described. Auto and cross correlation properties of some codes are mentioned according to obtained graphs. Also, importance of spreading codes on CDMA detection is mentioned. The main focus of this study is to emphasize the importance of code properties for detection. In other words, the effect of codes on DS-CDMA performance.

متن کاملIterative Multiuser Detection of Random CDMA Using Partitioned Spreading
Iterative joint detection of random CDMA is considered in conjunction with error control coding, in particular using low-density parity-check (LDPC) codes. The spreading sequences are partitioned into sections, called “partitioned spreading (PS)”, creating an artificial repetition code which interfaces the LDPC code with the multiple access channel. A suboptimal, but efficient cancelation proce...
متن کاملNetwork Performance of Asynchronous UTRA-like FDD/CDMA Systems using Loosely Synchronised Spreading Codes
In this paper we characterize the capacity of a UTRA-like Frquency Division Duplex (FDD) Code Division Multiple Access (CDMA) system employing Loosely Synchronized (LS) spreading codes. Current CDMA systems are interference limited, suffering from Inter-Symbol-Interference (ISI), since the orthogonality of the spreading sequences is destroyed by the channel. They also suffer from MultipleAccess...
