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 …

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

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 …

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 …

In this paper, we analyze the optimal (blockwise) subcarrier allocation schemes in single-
carrier frequency division multiple access (SC-FDMA) uplink systems without channel state …

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 …

Multi-carrier code-division-multiple-access (MC-CDMA) is a promising transmission
technique for high-speed wireless multimedia communication in frequency-selective fading …

This letter focuses on maximization of achievable throughput for uplink orthogonal frequency-
division multiplexing code-division multiple-access (OFDM-CDMA) systems. In particular, a …

Low Density Signature-Orthogonal Frequency Division Multiplexing (LDS-OFDM) has been
introduced recently as an efficient multiple access technique. In this paper, we focus on 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 …
