In our previous studies [1, 11], the impact of CP length on the cyclostationary features of signals and the difference between jamming signal and OFDMA signals are shown, respectively.
The avoidance of CTI is achievable by OFDMA HeNBs by properly assigning frequency resources among users in a bigger time scale or by self-organizing methods.
In this paper, a new swap-based algorithm was put forward to address the FDPS problem in OFDMA system.
Among these techniques, we can find MC-CDMA (Multicarrier-CDMA), OFDMA (Orthogonal FDMA), SC-FDMA (Single Carrier FDMA), and IDMA (Interleave Division Multiple Access).
Thus, a summary of the average capacity and average bit rate loss expressed in percentages for both the reference cell and the entire OFDMA network (i.
This paper proposes a multi-level priority-based sub-channel allocation scheme for OFDMA systems that considers both the optimized satisfaction of user requirements and the maximization of system accommodation capacity.
This paper focuses on the OFDMA resource allocation problem, specifying on IEEE802.
The block diagram for a downlink OFDMA is shown in Figures 4 and 5.
There are quite a large number of existing works on cross-layer scheduling design for OFDMA such as [1]-[4] and the optimal sub carrier allocation and the transmitter power adaptation in an OFDMA system having users with fixed data rate requirements have been studied in [1] & [2] respectively.
We remain committed to CDMA and OFDMA WAN modem leadership and the seamless and cost-effective commercialization of next-generation technologies around the world.
Nokia has agreed to assign ownership of a number of patents to Qualcomm, including patents declared as essential to WCDMA, GSM and OFDMA.
