|Title:||Qs-cdma Systems Using Concatenated Zcz Codes|
Baldini Filho R.
|Abstract:||The authors propose a novel use of zero correlation zone (ZCZ) codes to increase the performance of quasisynchronous code division multiple access (CDMA) systems. In this new approach, each spread sequence associated to a active user is a concatenation of two or more ZCZ sequences. In the receiver, each of the component sequences is separately correlated in order to recover the original information. A comparison to the convencional receiver is fulfilled by analyzing the performance of both schemes in a multipath Rayleigh fading channel and similar system parameters. © 2007 IEEE.|
