Large Deviations for Code Division Multiple Access Systems

open access: yesSIAM Journal on Applied Mathematics, 2002
Let us consider a problem from telecommunications. Suppose that a system has \(k\) users and that all users transmit data simultaneously. In oder to do so, each user multiplies his data signal by an individual coding sequence. At the receiver, the signal of the \(m\)th \((1\leq m\leq k)\) user can be retrieved by taking the inner product of the ...

Code division multiple access using Hermitean codes

Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications, 2002
Reed-Solomon (RS) codes present some desirable properties that make them useful in the generation of hopping sequences, for frequency hopping code division multiple access (FH CDMA). The algebraic geometric codes include the RS codes as a special case, therefore it is natural to propose the former as a candidate to FH CDMA.

Code Division Multiple Access

2002
As already described in section 2.2.3, a direct sequence SS system can provide code division multiple access. This is performed by assigning each user a different code for the spectrum spreading process. Under ideal conditions and if these codes are chosen properly, there will be negligible interference between different users despite the fact that ...

Coded multicarrier code division multiple access

Proceedings of 1995 IEEE International Symposium on Information Theory, 2002
This paper presents a multicarrier signaling technique for an asynchronous direct sequence (DS) code division multiple access (CDMA) system which employs linear convolutional codes to achieve performance gains in excess of path diversity gains realized in conventional single carrier RAKE DS CDMA systems.
