Achieving Frequency Reuse 1 in WiMAX Networks with Beamforming

Reuse 1 in WiMAX Networks with Beamforming

In this paper, we examine the performance of adaptive beamforming in connection with three different subcarrier permutation schemes (PUSC, FUSC and AMC) in WiMAX cellular network with frequency reuse 1. Performance is evaluated in terms of radio quality parameters and system throughput. We show that organization of pilot subcarriers in PUSC Major groups has a pronounced effect on system perform...

in English Multi-carrier Orthogonal Frequency Division Multiple Access (OFDMA) systems promise enhanced performance as compared to preceding single carrier ones. It is imperative to analyze the performance evaluation of these systems prior to network deployment which is approaching quite fast. Therefore, in this thesis we look into dimensioning issues related to OFDMA based system. The study of...

Synchronization Method of Broadcast Messages for Beamforming Performance in Mobile WiMAX Networks

We report that broadcast messages in Mobile WiMAX networks should be synchronized throughout all the base stations to gain the benefit of beamforming technique. A simple synchronization implementation of broadcast messages in Mobile WiMAX networks is presented. Using this technique, the interference between broadcast messages and beamformed messages can be reduced.

Optimization Algorithm of Resource Allocation IEEE802.16m for Mobile WiMAX

Multi user resource allocation is one of the key features towards high speed wireless network based on Orthogonal Frequency Division Multiplexing Access (OFDMA). According to IEEE802.16m (Mobile WiMAX) standard resource allocation problem has to be performed on a frequency and time two-dimensional space with the Physical and logical resource units (PRU and LRU) including Distributed logical res...
