Abstract
WiMAX communication system has spectrum alocation that
enable wireless service operator to operate throughout the world
including the rural area. WiMAX is suitable for development
country condition, where wiring infrastructures are limited. This
advantages make WiMAX become a desirable future wireless
technology that can be implemented in an developed archipelago
country like Indonesia.
WiMAX Communication System needs accurate channel
estimation process to predict fluctuative channel condition in order
to equalize received signal with the transmitted signal. Channel
Estimation recent studies, mostly analyzed the algorithm side
without considering implementation issue. The hardware
implementation of complex signal processing algorithm such as
MMSE(Minimum Mean Square Error) chamel estimation with
high computational complexity. are required to achieve robust
trasmission, whereas mobile wireless aplication require low power
dissipation. Therefore we need an algorithm mapping method to
the corresponding hardware architecture that practically fits with
overall system hardware. The proposed architecture aims to
achieve low power and efficient resource utilization by using
iterative memory shared architecture.
