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 …

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 …

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 …

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 …

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 …

In this paper, the problem of multi-user sub-carrier allocation by metric of channel gain in an
OFDMA system is formulated as an assignment problem in order to investigate an optimal …

This paper addresses the subcarrier allocation in downlink multicarrier direct-sequence
code-division multiple access (MC DS-CDMA) systems, where one subcarrier may be …

In the multi-carrier communication system physical channel environment between the user
and the base station are different, a reasonable allocation of sub-carriers in each user will …

In LTE/LTE-A orthogonal frequency-division multiple-access (OFDMA) systems, the number
of subcarriers is usually very high, upto 2048, and the number of simultaneously supported …
