Comparison of Receiver/Transmitter Algorithms for ODFMA with Dynamic Subcarrier Allocation
نویسندگان
چکیده
We consider the downlink of a multiuser MIMO-OFDMA system with different transmitter and receiver concepts, where subcarriers are assigned to users according to some metric. This metric describes the channel quality and the user with the highest metric at a subcarrier is allowed to transmit. The examined transmission schemes are shown to behave differently based on the chosen metric. Furthermore, the influence of channel coding on this behavior is investigated.

Power and Bit Allocation for Wireless OFDM Channels with Finite-Rate Feedback and Subcarrier Clustering
The study investigated the allocation of transmission power and bits for a point-to-point orthogonal frequency-division multiplexing channel assuming perfect channel information at the receiver, but imperfect channel information at the transmitter. Channel information was quantized at the receiver and was sent back to the transmitter via a finite-rate feedback channel. Based on limited feedback...
متن کاملOptimal Power Allocation with Partial Channel Knowledge for MIMO Multicarrier Systems
Closed-loop schemes optimizing power allocation can be applied if Channel Status Information (CSI) is available at both transmitter and receiver. However, CSI is never ideal and algorithms performance degrades rapidly when CSI is poor. In this contribution a MMSE cost function that takes into account channel uncertainty is proposed for MIMO systems with OFDM modulation. The derived algorithm is...
متن کاملDynamic Relay Selection and Resource Allocation in Cooperative Networks Based on OFDM
In this paper, we are planning to introduce a new method for relay selection and resource allocation in OFDMbased cooperative networks. Up to now, there have been relatively few works clearly concentrating on the combination of relay selection and resource allocation in such networks. In our work, a network with a single transmitter, a single receiver and a group of relays is considered. Relays...
متن کاملPhysical Layer Loading Algorithms for Indoor Wireless Multicarrier Systems
The demand for wireless networks has been growing rapidly over the recent past due to improved reliability, higher supported data rates, seamless connectivity between users and the access point, and low deployment costs relative to wireline infrastructure. This increase in demand started with the popular IEEE 802.11b wireless local area network standard. Many recent wireless network standards a...
متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
