The total transmission bandwidth and component

carrier aggregation proposed by LTE-Advanced, sets a new

challenge to the design of terminals. This article presents a way

to assure terminals cope with the large bandwidth in an efficient

manner. Various filtering methods are explored showing that an

SDR architecture, such as ADRES (Architecture for Dynamically

Reconfigurable Embedded Systems), is suitable for dynamic

adaptation of filtering methods as function of the aggregation

scheme and the individual bandwidth assigned to each terminal.

This method is able to reduce the processing load by 70%

for LTE-A with legacy support and possibly higher reduction

when LTE legacy is not supported. Simulations conclude that the

performance loss derived from the proposed method is marginal

with no negative repercussion on the posterior baseband stages.
