Abstract |
|
The WiMAX is a rapidly developing technology for broadband wireless access system. The resource allocation problem in OFDMA system is how to assign Burst to multi-users. OFDMA resource allocation algorithms manage the distribution and assignment of shared OFDMA resources among the users serviced by the base station. The OFDMA resource allocation algorithms determine which users to schedule, how to allocate subcarriers to them, and how to determine the appropriate power levels for each user on each subcarrier. It is require doing performance analysis of Burst Mapping algorithm on a WiMAX downlink OFDMA subframe structure subject to minimizing the wastage of bandwidth. Variable length Burst mapping algorithm tries to allocate burst across several subframe so that the bandwidth wastage can further be decreased. |
