Multi carrier modulation techniques such as MC-CDMA are used in high-speed
communication applications. Due to MC-CDMA being a multiuser in technology, the …

Sub-carrier allocation is an important process that directly affects users data and bit error
rates for multi-user multicarrier systems. The most important feature of the allocation process …

One of the most important issues to be taken into consideration in multi carrier
communication systems with multi users is the assignment of the available resources to the …

Subcarrier allocation for multiuser MC-DS-CDMA systems is much more complicated when
compared to OFDM systems due to the presence of multiple access interference (MAI) when …

This paper introduces a new adaptive subcarrier assignment criterion for downlink grouped
Multi Carrier-Code Division Multiple Access (MC-CDMA) systems. The target of the …

In MC-CDMA systems, subcarriers can be shared by different users. In this letter, we exploit
the shared nature of subcarriers and propose a user grouping and subcarrier allocation …

For future systems of wireless communication, multi-carrier code division multiple access
(MC-CDMA) is becoming much attractive due to its high data rate and multiple access …

(MC-CDMA) is becoming a very attractive multiple access technique for high-rate data
transmission in the future wireless communication systems. This paper is focused on …

We propose a subcarrier allocation scheme for multiple access MC-DS-CDMA systems,
where random signature sequences are used to identify the users. The optimal solution to …

Multicarrier code-division multiple-access is one of the effective techniques to gain its
multiple access capability, robustness against fading, and to mitigate the ISI. In this paper …
