Description: OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.

Description: — Performance comparison of multiuser OFDM-TDMA and
OFDMA systems by considering physical and link cross-layer behavior
is conducted in this work. We provide a new framework for performance
evaluation that centers on “ scheduling” with several different
subcarrier/bit allocation schemes. The performance metrics include: the
bit rate, the bit error rate (BER), packet throughput and delay. The
instantaneous channel conditions of users are assumed to be available
at the base station, which can be achieved by channel estimation at the
mobile terminal (MT), and then fed back to the base station through
a control channel. To perform the link layer comparison, we model the
Rayleigh fading channel with a nite-state Markov chain, and adopt the
M/G/1 queueing model as the analytical tool. Computer simulation is
performed to verify conducted analytical results-— Performance comparison of multiuser OFDM-TDMA and

Description: Relaying and orthogonal frequency division multiple
access (OFDMA) are the accepted technologies for emerging
wireless communications standards. The activities in many
wireless standardization bodies and forums, for example IEEE
802.16 j/m and LTE-Advanced, attest to this fact. The availability
or lack thereof of efficient radio resource management (RRM)
could make or mar the opportunities in these networks. This
paper therefore provides a comprehensive RRM algorithm for
OFDMA-based multi-cellular fixed relay networks in a way to
ensure fairness among users with minimal impact on the network
throughput (in contrast, pure opportunistic RRM techniques
always favor users with good channel conditions
